This paper focuses on congestion control but while previous works considered scalar sensor nodes which only report events in the size of a few bytes, we are addressing congestion control for information-intensive flows such as video flows for surveillance applications in pervasive wireless multimedia sensor networks. The proposed framework that we describe in this paper tries to put several mechanisms...
During the past few years, wireless mesh networks have drawn significant attention from academia and industry as a fast, easy, and inexpensive solution for broadband wireless access. In WMNs it is important to support video communications in an efficient way. To address this issue, this article studies the multipath routing for multiple description video delivery over IEEE 802.11-based WMNs. Specifically,...
In this paper, we propose a multipath routing algorithm (EDB-MRA) on the basis of directed diffusion for wireless sensor networks. The algorithm establishes multiple paths from source node to destination node. According to the three metrics of network link - energy consumption, delay and bandwidth, each path can be given a choices probability to make data always transmit on multiple paths of better...
