HelloMsgC: A Practical Implementation of Hello Message Protocol in Wireless Sensor Network

摘要

In Wireless Sensor Networks, the basic element of communication among the sensor nodes is Hello Message protocol, through which a node knows their neighbouring nodes before making communication. We present, HelloMsgC: Implementation of Hello Message Protocol-A practical demonstration with IRIS motes in TinyOS programming with nesC language. A sensor node broadcasts hello message request to know its neighbouring nodes if any, within its radio range. The nodes who listen to this request replies to by sending the request acknowledgement.
