| Abstract | Abstract-As the name suggests SPIDERNET (Sensor Platform for Intelligent aD-hoc wireless Relaying NETwork) is a platform for a wireless sensor network developed at TU Dresden. Sensor networks can typically be distinguished by their extreme energy constraints and their low data rate. To conserve expensive energy long sleep periods are inevitable. Contrary, for reliable multihop communication nodes have to be active. This paper describes the hardware of SPIDER-NET. Derived from hardware demands a protocol for non-time critical indoor surveillance was developed and implemented, which is described as well. Consecutive analysis gives insight into energy consumption, probability of collision and feasible network sizes. The heart of the paper is the protocol which combines ideas from known proposals: rotating cluster heads (CH) ensure energy balancing, knowing only the schedule of immediate neighbors minimizes protocol overhead and ensures welldefined active times, a fixed superframe structure guarantees latency requirements. For channel access occasional collisions are tolerated while avoiding signaling overhead. I. |
