The objective of this work is to investigate the role of protocol self organization at the Medium Access Control Layer in wireless ad hoc and sensor networks. While the traditional wired networks continue to enjoy relatively stable operating environments, the emerging wireless and sensor networks suffer from the operating instabilities of adjusting operating parameters and state machine logic due to their ad hoc deployments, specialized applications and various resource constraints. In order to utilize protocol reorganization to mitigate the instability effects, we propose a MAC self...
