Ideally in Wireless Sensor Network (WSN), the bandwidth (usually a single channel) and the radio transmission range are set to 250Kbps and 40m respectively to ensure error free communication. However, dense deployment of sensor exposes them to various sources of problems such as transmission error and link failure, which eventually leads to high retransmission rate that results in increased congestion, overhead, and delay in the limited shared channel thus hindering network performance. This paper investigates via simulation, the effect of increasing traffic under various bandwidth capacity in a multi-hop network operated using a state free cross-layer based routing protocols, which perform the lazy binding technique when routing. Extensive experiments undertaken on the state-free protocols have shown that the low channel capacity yields higher packet delivery ratio when compared to the higher bandwidth capacity, which is more exposed to interference and congestion. |
