A hybrid optimization technique for Deployment and routing in wireless Sensor networks

Abstract

newlineWireless Sensor Networks WSN is one of the most important technologies newlineof this century Its design is influenced by many factors such as transmission errors newlinenetwork topology and power consumption Consequently developing a WSN newlineapplication introduces several implementation challenges This thesis describes the newlinedeployment and routing problem which is the most fundamental issue in WSN newlinedesigning newlineSensor network deployment is very challenging due to the hostile and newlineunpredictable nature of environments The field coverage of WSNs can be enhanced newlineand consequently network lifetime can be prolonged by optimizing the sensor newlinedeployment with a finite number of mobile sensors The proposed deployment newlinealgorithm provides a decision and control mechanism at each node to be used during newlinedeployment rather than random diffusion which is used in the previous work newlineIn contrast to existing algorithm which uses an incremental approach the nodes in the newlineproposed algorithm are deployed at the same time and they organize themselves in an newlineadaptive manner Unlike the existing algorithm this proposed algorithm does not newlinerequire prespecified destinations to form an energy efficient topology newline newline
