Hi,
I am trying to build a wirless sensor network using zigbee. The network will consist of four nodes that have certain sensors on them. Each node will transmitt its sensor information to be received by the rest. There is only one channel allocated, so frequency multiplexing is not allowed. I have no experience with wireless tranmission protocols. I am looking for a simple and effecient protocol which can avoid collisions and work with n nodes(ad-hoc capabilities would be a bonus). Any help is much appreciated.
