ABSTRACT
Example standardized sensor node platforms have been developed and deployed, and custom hardware has also been used to meet the energy and performance constraints of specific situations. The intent and objectives of a deployment suggest many different organizing paradigms for sensor networks, although a very common architecture for sensor networks, due mainly to the limited range of individual transceivers, requires nodes to collaboratively forward data on behalf of their

peers via multihop routing. Some situations in which nodes are static and node failure rates are low concentrate upon initiating long-lived routes with an explicit establishment phase, while others favored in more dynamic and less predictable environments, such as wildlife-monitoring protocol mentioned previously by Juang et al. [3], concentrate upon database merging via flooding to deliver messages progressively to the sink node.
