Wireless sensor network (WSN) is a system composed of a large number of low-cost micro-sensors. This network is used to collect and send various kinds of messages to a base station (BS). WSN consists of low-cost nodes with limited battery power, and the battery replacement is not easy for WSN with thousands of physically embedded nodes, which means energy efficient routing protocol should be employed...
Recent research has shown that the performance of opportunistic routing and network coding in wireless networks is greatly impacted by the correlation among the links. However, it is difficult to measure the correlation among the links, especially because of the time-varying behavior of the wireless links. Therefore, it is crucial to design a distributed algorithm that does not require the explicit...
Cooperative communication (CC) has been proposed recently as an effective way to mitigate channel impairments. It has been shown that cooperative communications have the potential to significantly increase the capacity of wireless mesh networks (WMNs). However, most of the works focus on single channel based WMNs. In this paper, we will demonstrate how the cooperative communication benefits multi-channel...
In this paper, we explore a quantitative approach to accountable wireless multi-hop networks. We propose using hierarchical P-Accountability to adapt the requirements of modeling a complex network environment and assess the degree of accountability in a fine-grained manner. We have defined P-Accountability and demonstrated its use in the hierarchical network environment. In addition, we apply P-Accountability...
