We propose an approach for opportunistic forwarding that supports optimization of multipoint high volume data flow transfer while maintaining high buffer availability and low delays. This paper explores a number of social, buffer and delay heuristics to offload the traffic from congested parts of the network and spread it over less congested parts of the(More)
This paper describes the design, development and evaluation an interest driven overlay on the top of our congestion aware forwarding protocol (CAFe) for social opportunistic networks. We show that P2P filecasting on top of Cafe achieves high success ratio of answered queries and high availability of intermediary nodes while maintaining fast downloads.
— Detecting and dealing with congestion in delay tolerant opportunistic networks is an important and challenging problem. In this paper we describe CAFREP, a unified congestion control framework for routing in such networks that adapts both data sending rates and data forwarding policies through a novel reactive fully distributed approach. CAFREP enables(More)
BACKGROUND Involving service users in planning their care is at the centre of policy initiatives to improve mental health care quality in England. Whilst users value care planning and want to be more involved in their own care, there is substantial empirical evidence that the majority of users are not fully involved in the care planning process. Our aim is(More)
