Evaluating energy consumption on low-end smartphones
(2015)
The relationship between battery consumption in
smartphones and the usage statistics of a phone is direct. Modern
smartphones, even low-end, are equipped with multiple wireless
technologies, e.g. GSM, 3G, WiFi and ...
Investigating battery consumption in low- end smartphones: preliminary results
(International Information Management Corporation, 2017)
Due to lack of electricity in the rural communities of Africa, users often
have to incur extra expense on recharging their mobile phones. The limited battery
capacities of low-end smartphones, therefore, present a barrier ...
Towards communication and information access for deaf people
(SAICSIT, 2014)
In tightly circumscribed communication situations, an interactive system resident on a mobile device can assist Deaf people with their communication and information needs. The Deaf users considered here use South African ...
Mobile vertical handover between infrastructure and ad hoc Wi-Fi networks
(Telkom, 2011)
This paper addresses mobility management issues in an environment with both wireless LAN and wireless mesh networks. We first examine wireless mesh network client side transparency within mesh mobility management protocols ...
Investigation of a dual-band dual radio indoor mesh testbed
(2018)
Scalability of community wireless mesh networks in terms of mesh nodes and mobile end-users along with their anticipated usage profile remains unexplored territory. However, conducting such experiments on a live community ...
Improving usability and correctness of a mobile tool to help a Deaf person with pharmaceutical instruction
(ACM, 2013)
The computing for development community knows how to build user interfaces using qualitative methods for text il- literate users, especially on mobile devices. However, lit- tle work has been done speci cally targeting ...
Situation-aware routing based on link quality for static mesh networks with mobile nodes
(Telkom, 2011)
Situation-aware routing seeks to improve quality of service on hybrid wireless mesh networks by making routing decisions based on the current situation of the network. BATMAN-adv is a mesh routing protocol that counts ...
