Abstract
The effective use of sensor node battery is crucial for wireless sensor networks (WSNs). Based on a realistic power consumption model for wireless communications, we consider in this paper the low-power-consumption design for multi-hop routing in WSNs. To this end, we first mathematically study the dependence of communication power consumption of a multi-hop route on the relay node placement. Theoretical derivation reveals that in order to minimize the communication power consumption, the relay nodes should be uniformly placed along the line segment connecting the route ends. Utilizing these results, we then proceed to perform a numerical analysis on the relationship between communication power consumption and the number of relay nodes in the route. It is found that the optimum number of relay nodes is almost linearly proportional to the route length from the source node to the sink node. Computer simulations corroborate the theoretical results.
