Wireless sensor networks typically consist of a large number of sensor nodes with limited onboard battery resources which are difficult to recharge or replace. Thus the reduction of energy consumption for end-to-end data rate and maximization of network lifetime have become chief research concern. In recent years, many techniques have been proposed for improving the energy efficiency in wireless sensor networks. Among these techniques, V-MIMO technique has been considered as one of the effective
INTRODUCTION Wireless Sensor Network consists of highly distributed Autonomous sensors nodes to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the network to a receiver (destination) [1] [7]. A sensor node consist of a radio transceiver with internal antenna or connected to external antenna, a microcontroller and electronic circuits for interfacing with the sensors and energy source
clustering protocols aim is to minimize the energy consumption for each node and to maximize the network lifetime of wireless sensor networks. In wireless sensor networks the node are densely deployed and it consumes large energy, it acquires from cluster formation overhead and fixed level clustering.

design issues in Wireless Sensor Networks (WSNs). For that reason, it is vital to consider network coverage and energy consumption in the design of WSN layouts. Because selecting the optimal geographical positions of the nodes is usually a very complicated task, we propose a novel heuristic search technique to solve this problem. Our approach is a multi-population search algorithm based on the Particle Swarm Optimization (PSO). The goal of this algorithm is to search for sensor network layouts that
connecting with the wireless sensor network. The bandwidth consumption and energy effectiveness of wireless sensor networks is limited no longer usage and is eliminated by the data aggregator of wireless sensor networks. The data is collected from all the other nodes and this data is transmitted to the wireless nodes by the cluster node. To minimise the traffic congestion or traffic flow we choose the algorithm, which will automatically choose the shortest path in the wireless network for generating the
INTRODUCTION A wireless sensor network (WSN) is a network consisting of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, humidity, motion or pollutants and to cooperatively pass their data through the network to a main location. The WSN is built of nodes from a few to several hundreds or even thousands, where each node is connected to one (or sometimes several) sensors. Each such sensor network node has typically
A wireless sensor network (WSN) is composed of a group of small power-constrained nodes with functions of sensing and communication, which can be deployed in a huge area for the purpose of detecting or monitoring some special events and then forwarding the aggregated data to the designated data center through sink nodes or gateways. In this case, the network connectivity and the sensing coverage are two of the most fundamental problems in wireless sensor networks. Designing an optimal area coverage
