Wireless Sensor Networks (WSNs) comprise of large number of sensor nodes, which sense and measure various physical phenomena related parameters and transmit the measured data towards the base station by making use of the neighbouring nodes acting as relay nodes. In order to extend the lifetime of a WSN application, it is necessary to distribute the energy dissipated among the nodes evenly in the network...
The Wireless Sensor Networks (WSNs) after their emergence have triggered many active research areas; not because of low-scale hardware design but also due to a wide spectrum of its potential applications being in day-to-day areas of our life. However, because of the ubiquitous and pervasive computing paradigm that the WSNs foster and because of the resource constrained characteristic, security &...
An energy efficient routing protocol is the major concern in Wireless Sensor Networks (WSNs). In this paper, we describe LEACH routing protocol and some of its new versions. After that we propose an energy efficient hierarchical routing protocol, developed from LEACH. The basic concept involved in increasing energy efficiency and hence lifetime is to keep radio communication distance as minimum as...
The optimal number of cluster heads is an important parameter of wireless sensor network performance. Network nodes will consume more energy if the number of cluster heads is too much or too little. This paper focuses on novel calculation method for optimal number of cluster heads. Base on the analysis of LEACH energy dissipation model, novel calculation method is derived from the total energy dissipation...
In sensor networks, clustering protocol such as LEACH is an efficient method to increase whole networks lifetime. However, this protocol result in high energy consumption at the cluster head node. Hence, this protocol must changes the cluster formation and cluster head node in each round to prolong the network lifetime. But this method also causes a high amount of energy consumption during the set-up...
One of the weaknesses of wireless sensors networks (WSN) is the limit of energy which affects networkpsilas lifetime. To increase the lifetime of the sensor network, this paper suggests a new routing approach which combines two algorithms: LEACH and PEGASIS. In our proposal, nodes belonging to the same cluster form a chain where nodes communicate only with their closest neighbors, so that energy dissipation...
