Designing an energy efficient algorithm is one of the most important challenges in wireless sensor networks (WSNs). In this paper, we present a node sleeping algorithm based on the minimum hop routing protocol to minimize energy consumption. The proposed scheme divides all the nodes except the sink node into terminal nodes and intermediate nodes according(More)
In ZigBee wireless networks that use DAAM (Distributed Address Assignment Mechanism), the scheme may prohibit a node from accepting a child by network parameters. To address the problem, we propose BAIR (Borrowed Address Assignment based on Inheritance Relation) algorithm. Firstly the orphan is divided into the orphan router and the orphan end device, then(More)
In ZigBee networks, the classical Tree Routing algorithm only utilizes the father-child relationship between nodes to establish routes, thus the path usually may not be optimal, which leads to some extra overhead. To address this problem, in this paper, we propose an improved Tree Routing algorithm which utilizes the information of neighbors within two(More)
