Considering the great significant role that routing protocols play in transfer rate and choosing the optimum path for exchange of data packages, and further in the amount of consumed energy in the routing protocol, the present study has focused on developing an efficient compound energy algorithm based on cluster structure which is called active node with cluster structure. The purpose of this ...

Due to deployment in hostile environment, wireless sensor network is vulnerable to various attacks. Exhausted sensor nodes in sensor network become a challenging issue because it disrupts the normal connectivity of the network. Affected nodes give rise to denial of service that resists to get the objective of sensor network in real life. A mathematical model based on Absorbing Markov Chain (AMC...

An efficient cluster head selection algorithm in wireless sensor networks is proposed in this paper. The implementation of the proposed algorithm can improve energy which allows the structured representation of a network topology. According to the residual energy, number of the neighbors, and the centrality of each node, the algorithm uses Fuzzy Inference Systems to select cluster head. The alg...

Sensor Network (SN) is similar to a general purpose Mobile Ad-Hoc Network (MANET) in a lot of aspects, they are distributed, self-organized, multihopped, lack of fixed infrastructure. The main difference lies in that fact that the former basically has lower cost, slower rate bandwidth, and higher redundancy, and are more power-constrained, Thus almost all of the previous efforts have been put o...

Industrial Wireless Sensor Network (IWSN) is the recent emergence in wireless technologies that facilitate industrial applications. IWSN constructs a reliable and self-responding system using interconnected intelligent sensors. These sensors continuously monitor analyze process to evoke its best performance. Since are resource-constrained communicate wirelessly, excess sensor placement utilizes...
