For the requirements of energy saving in wireless sensor networks (WSNs), this study proposes a transmission power control strategy for cluster heads (CHs) based on multi-packet reception in clustering WSNs. First, this study proposes a new CHs selection algorithm for clustering WSNs. Second, transmission power levels of each CH are determined according to the number of CHs in monitoring area. Third,...
Anycast is a mechanism that the source node sends the data groups to the nearest sink node. The paper proposes a communication model of implementing an Anycast service for deploying several sinks in wireless sensor network. We propose a novel anycast tree-based approach to reduce the mutual interference and minimize the energy consumption. Here the nodes as the anycast node form a tree with a sink...
A reliable and efficient clustering algorithm in wireless sensor networks is proposed, which can allow the structured representation of a network topology. According to the residual energy, number of the neighbors, and centrality of each node, the algorithm uses fuzzy petri nets to select cluster head. The algorithm not only balances the energy load of each node, but also provides global reliability...
Clustering is an effective approach to hierarchically organizing network topology and to prolong the lifetime of a wireless sensor network. Current clustering protocols usually utilize two techniques: selecting cluster heads with more residual energy and rotating cluster heads periodically to distribute the energy consumption among nodes in each cluster. Most of the researches in this field has focused...
In this paper, we introduce a novel routing algorithm which is based on ant colony system. The objective of this novel algorithm is to solve the problem of energy and congestion control on wireless sensor network routing process. This novel algorithm is able to achieve better load balance and prolong the network lifetime. In this novel algorithm we combine the pheromone released by multi-ant colonies...
In this paper, we propose a new routing algorithm which can increase the network lifetime. We assume that each node can estimate its residual energy and then a new clustering method will be proposed for increase of network lifetime. This assumption is similar to many other proposed routing algorithms for WSN and is a possible assumption. In the new method, the predefined number of nodes which have...
Cluster-based routing scheme is able to prolong the network lifetime and save the energy consumption. In this field, many cluster-based routing protocols are proposed such as LEACH, TEEN, APTEEN, and so on. On the other hand, the chain-based routing protocols construct the chain such as PEGASIS and concentric-clustering routing scheme. The concentric-clustering routing scheme is the multiple-chain...
