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. We introduce the ad-hoc, multi-hop protocol implemented on our hardware platform. It combines ideas from known proposals: rotating cluster heads (CH) [1] ensure energy balancing, knowing only the schedule of immediate neighbors minimizes protocol overhead and ensures well-defined active times while minimizing idle listening and overhearing, a fixed superframe structure guarantees latency requirements. For channel access occasional collisions are tolerated while avoiding signaling overhead.
