Resource Utilization of Multi-hop CDMA Wireless Sensor Networks with Efficient Forwarding Protocols

In this paper, we propose a new forwarding scheme for a multi-hop CDMA wireless sensor network (WSN). Selection of intermediate nodes considers detection probability along with maximum forwarding distance by taking into account the wireless channel condition, like path loss, and shadowing. Energy and latency performance using infinite ARQ between source and final destination of proposed scheme is studied. Performance of this scheme is compared with nearest neighbor based routing scheme, where an intermediate node in the route selects the nearest node within a sector angle, considered as search angle, towards the direction of the destination as the next hop. Further a frame work for packet size optimization based on resource utilization, capturing both energy consumption and delay, is presented.
