Energy conservation is one of the most important issues in wireless ad hoc and sensor networks, where nodes are likely to rely on limited battery power. Many new algorithms have been proposed for the problem of routing data in sensor networks. In this paper, the authors propose a new forwarding technique where nodes are placed in a random fashion maintaining a minimum distance between any two nodes and study its performance on a multi-hop CDMA Wireless Sensor Network (WSN). A new routing protocol where selection of intermediate node is based on a metric combining detection probability and maximum forwarding distance towards the sink is proposed to reduce retransmissions in a wireless channel impaired by path loss and shadow fading.
