Network splitting requires novel routing scheme different from traditional storage and forwarding manner. In the split wireless sensor networks, message ferrying method can be introduced to provide normal communication for network within tolerable delay. The definition of network delay and packet loss rate in such routing protocol was brought out. The computation method of indexes was also provided...
A clustering routing algorithm for wireless sensor network (WSN) based on improved ant colony algorithm is proposed in this paper. This proposed algorithm is based on the advantages of clustering algorithm and ant colony algorithm, which applies improved ant colony algorithm to the clustering algorithm, in order to find the best path from cluster head to sink. To improve ant colony algorithm, the...
In recent years, many clustering algorithms have been proposed to solve the problem of routing. However, many of these algorithms have the problem of uneven load of cluster heads. In this paper, we present an algorithm - the maximum balance cluster head energy consumes of routing (MCR) - to solve the above problem. In our proposed MCR algorithm, when ordinary nodes receive broadcast information from...
The performance of the Wireless Sensor Networks (WSNs) is strongly affected by the limited capacity of the sensor nodes which form these networks. In fact, this limited capacity has a great influence on the lifetime of the wireless sensor networks. So an effective management of the consumed power of the nodes can increase the network lifetime. Various algorithms have been proposed to optimize the...
In wireless sensor networks, the size of backbone network have a great impact on communication overhead, as well as the network lifetime. It can be designed based on cluster tree. MIS (maximum independent sets) composed of clusterheads is achieved by clustering algorithm, based which MCDS(minimal connected dominating sets) and MST(minimum spanning tree) are built with improved Prim algorithm, and...
