Flooding tree construction has been widely investigated. However, these existing flooding trees normally could not achieve low latency and high energy efficiency at the same time which is critical to data transmission, especially in low-duty-cycle WSNs with unreliable wireless links. In this work, we propose an efficient local energy optimization algorithm (LEOA) for minimum-delay flooding tree in...
Energy efficient multicast routing is one of the fundamental problems in wireless sensor networks (WSNs). Previous work has shown that when the goal is to find multicast trees with minimum transmission cost, the problem becomes NP-complete. In this work, we present a heuristic distributed minimum transmission multicast routing protocol (MTMRP) for WSNs. By introducing the biased backoff scheme and...
Cooperative diversity can be applied to energy-constrained resource-constrained wireless sensor network s to significantly reduce node energy consumption. However, cooperation synergy must be carefully selected and coordinated to practically exploit this energy saving potential. In this paper we investigate synergy choice for energy minimization algorithm in a resource-constrained wireless sensor...
