Prolonging lifetime of directional sensor networks is one of the hot topics these days because of vast application of these kinds of sensors. Since, the depletion of energy from one sensor indicates a lack of information being communicated from one part of the network. Hence, managing energy consumption of each sensor becomes critical. In this paper one approach for improving sensor network lifetime...
Energy efficiency is a critical consideration in the design of low cost sensor networks. This paper studies the problem of extending the lifetime of the sensor networks as far as possible while maintaining the quality of network coverage. A systematical analysis on the relationship between the network lifetime and cover sets alternation is given, and by introducing the concept of time weight factor,...
In this paper, we consider the important aspect of quality of service (QoS) in wireless mesh networks, focusing on packet delays and packet drops. We observe that the options of solely focusing on throughput, and of only depending on the QoS type characterization by the application level protocol is not sufficient. We propose the use of multiple queues to hold the packets based on their QoS requirement...
