In the application of wireless sensor networks (WSNs), energy efficiency is always an important topic for extending the network lifetime. Scheduling the operation modes of sensors can reduce the energy wasted by redundant sensors, but frequent alterations of sensors' modes and different data transmission routes influence the reliability of the WSN. In this paper, a novel algorithm for maximizing the...
Broadcast is very important for delivering messages in wireless sensor networks. In order to improve the efficiency of broadcast and reduce energy consumption, it is necessary to construct a virtual backbone within the entire network. Constructing a virtual backbone is identical with calculating connected dominating set. 1-hop neighbor node transmission coverage information is used to calculate the...
This paper considers the problem of link scheduling with non-preemptive constraint in wireless mesh networks. In real-world implementation, there is often a constraint that a link can only transmit once and occupy consecutive time slots during a frame. We refer to it as the non-preemptive constraint. To date, only few scheduling algorithms in the literature has taken such constraint into consideration...
