Recently, research on wireless sensor networks (WSNs) has received a lot of attention because they offer an advantage of monitoring various kind of environment. The management of sensors' energy is a very important problem in wireless sensor network. Research has shown a significant contribution to increase the network lifetime and improve its performance is due to energy conservation. The goal of...
Given the fact that LEACH protocol didn't take the residual energy of nodes into account when choosing the cluster heads, which may result in the node with rather low energy to be chosen as a cluster head. Thus, it will cause the cluster created by this low-energy node to be dead at an early stage, which wastes the whole network's resource. Here in this paper, we introduced an energy factor when choosing...
Wireless Sensor Network (WSN) has recently emerged as a new widely used technology. However, the deployment of such networks has reported high rates of failures. Due to resource constraints of sensor nodes, the design of efficient failure detection techniques has become a very challenging issue. Already proposed WSN fault detection protocols have reported either a high number of false suspicions,...

Forest is one of the most valuable and indispensible natural resource. The forest fire is one of the natural disasters that destroy the forest not only in India but countries like Australia, USA etc which is called as bush fire, wild fire respectively. Now in terms of deploying Wireless Sensor Networks for forest fire monitoring and detection, there is a need to investigate appropriate routing protocol...
A WSN consist of a large number of small, low cost devices called sensor nodes deployed in an area. These sensor nodes are used for the purpose of monitoring different physical parameters of that particular area. The sensor nodes consist of a low power, irreplaceable battery which has a limited lifetime. To achieve long lifetime of the sensor network, it is necessary to reduce energy consumption by...
Wireless Sensor Networks (WSNs) are a promising technology to monitor distant or inaccessible areas. As nodes have a limited energy supply, many routing protocols are based on a clustering mechanism: some nodes are elected as cluster heads and have to deal with most of the communication burden of the network, while the other nodes perform only simple operations. In this paper, we propose a new election...
Wireless sensor network (WSN) is composed of tiny nodes. The nodes are deployed randomly over an area in order to sense various physical phenomena related parameters. The nodes sense the data within their vicinity and forward the data to the neighboring nodes so as to forward the data towards the base station. However, there may be few malicious nodes present in the network and these nodes falsify...
