In this paper we simulate a multi-hop self-organizing wireless

sensor network. The purpose of the simulation is to investigate,

quantitatively, the performance of our self-organizing network

design. In particular, we examine such parameters as network

formation time, data packet delivery performance, throughput,

and device duty cycle. In addition, we analyze the impact of

MAC and low-duty cycle protocols. We demonstrate that our

tree network has the capability of automatic network formation,

update, and recovery. The design also supports simple address

assignments and straightforward routing. We discuss our

approach, OPNET simulation design, and simulation results
