- ItemOpen AccessInter-subnet localized mobility support for host identity protocol(Springer, 2011) Muslam, Muhana; Chan, H Anthony; Ventura, NecoHost identity protocol (HIP) has security support to enable secured mobility and multihoming, both of which are essential for future Internet applications. Compared to end host mobility and multihoming with HIP, existing HIP-based micro-mobility solutions have optimized handover performance by reducing location update delay. However, all these mobility solutions are client-based mobility solutions. We observe that another fundamental issue with end host mobility and multihoming extension for HIP and HIP-based micro-mobility solutions is that handover delay can be excessive unless the support for network-based micro-mobility is strengthened. In this study, we co-locate a new functional entity, subnet-rendezvous server, at the access routers to provide mobility to HIP host. We present the architectural elements of the framework and show through discussion and simulation results that our proposed scheme has achieved negligible handover latency and little packet loss.
- ItemOpen AccessTEDI 3 Week 2 - Orientation and Mobility and Daily Living Skills(2019-12-01) Botha, Michelle; Dzapasi, GoldenIn this video, Michelle Botha and Golden Dzapasi discuss the importance of physical mobility and daily living skills in assisting people with visual disabilities in participating fully in the social, cultural, economic and political life of South Africa. Michelle discusses how visually-impaired people experience difficulties navigating a built environment that is not designed with accessibility in mind, as well as experience difficulties in a communicative culture that is largely visual in nature. Michelle and Golden discuss how education can be adjusted to teach concepts that would be learned incidentally in a more intentional way. They discuss the full range of skills (such as gross and fine motor skills), directional indicators, different surfaces, and other aspects such as traffic and travel that visually-impaired learners will need to grasp in order to function as full members of society. They close by discussing how teachers (and parents and other professionals) can model and encourage the development of these skills at school and at home.
- ItemOpen AccessWater and sociality in Khayelitsha: an ethnographic study(2022) Kongo, Minga Mbweck; Nyamnjoh, Francis; Chitonge, HormanThis study examines forms of social relationships created around unequal municipal water distribution in South Africa. Using the case of Khayelitsha, the study investigates residents' use of water to sustain their livelihood and build personhood. Water mobilises the formation of relationships in myriad ways. How residents, collectively and individually, imagine, negotiate and construct their future pathways around resources available to them in a social group is explored. Ethnographic tools are used to address how social formations are created around municipal water in Khayelitsha. The study looks into how inequalities related to access to water in Cape Town are produced with inequitable development patterns. Using incompleteness and conviviality as framework, the study seeks to understand how ideas of social formation, belonging, marginality, and physical and social mobility are produced, reproduced and contested around water. By focusing on the strategies deployed by residents, this study also seeks to describe the challenges of inadequate water access experienced by residents in less- provisioned areas. The multiple relations with, and complexities of, municipal water are chronicled, as well as how Khayelitsha residents think about, relate and respond to water. The empirical data reveal several structural issues characterising the formation of social relations: incompleteness, impoverishment, marginalisation, water access and minimal opportunities. Despite many challenges, frustration, and heavy reliance on communal taps, tanks, water trucks, and hydrants, shack dwellers particularly cherish an ideal of self-sufficiency with the limited amount of water they access. In this quest, they maintain social relations and resistance to the political economy of water. They achieve this by mobility from one settlement to another, maintaining a strong sense of community, belonging, social relationships, and household interdependence, connected to a sense of incompleteness and, to a more considerable extent, Ubuntu. This social practice is manifested in various forms: neighbourliness, water usage at communal points, land occupations, and strikes, amongst others. By combining the structural issues and aspects of social practices provided above, water is seen as a substance that constructs social formations through the phenomena of incompleteness and conviviality. The data were collected during several field visits between February 2020 and March 2021 through observation of interactions and participation in residents' social activities and formal and informal interviews and group discussions with a representative sample of residents in Khayelitsha.
- ItemOpen AccessWriting Your World Week 2 Video 1 - Recap on Identity(2019-06-01) Nomdo, Gideon; Hunma, AditiThis video focuses on recapping the issues surrounding identity. The video touches on how the Soweto youth engages in a ritual as a way of asserting their identity. The video then moves onto the themes of mobility. It explores how identity changes when people move between contexts. The video also touches on how new insights from DNA results affect their identity and mobility. This is video 1/10 in week 2 of the Writing your World course.
- ItemRestrictedWriting Your World Week 3 Video 1 - Recap on identity and mobility(2019-06-01) Nomdo, Gideon; Hunma, AditiThis video focuses on the intersection of identity and mobility. It restates all the work that has been done so far in the course with the regards to how individual's mobility affect their identity. The video then introduces a new theme: culture. It defines what culture is and how it is important to our identities. it then touches on how culture can provide a point of reference when writing the essay on identity. This is video 1/12 in week 3 of the Writing your World course.
- ItemOpen AccessWriting Your World Week 3 Video 9 - Student writers drafting their paragraphs(2019-06-01) Nomdo, Gideon; Hunma, AditiThis video focuses on the process of the students drafting their paragraphs. The video observes how the different students discuss the themes of identity and linking it to mobility and culture in their paragraphs. The video looks at whether each student has presented their ideas convincingly. Ada's uses her experiences growing up in her arguments. Ziggy draws on the works of Sichone and Blommeart in his arguments alongside his experiences and the history of his people. Joey makes use of sexual orientation as a different perspective of looking at identity. This is video 9/12 in week 3 of the Writing your World course.
