Off-Network Control Processing for Scalable Routing: A Novel Paradigm for Scalable Design in Very Large Sensor Networks
OffNetwork Control Processing for Scalable Routing A Novel Paradigm for Scalable Design in Very Large Sensor Networks Author:Tao Wu In this book we investigate two problems concerning wireless sensor networks: (A) energy efficient medium access control and (B) scalable routing architecture for very large wireless sensor networks. Regarding to the first problem , we propose a Self Reorganizing Slot Allocation (SRSA) mechanism for a TDMA-based medium access control (MAC)... more » protocol. The primary contribution is to demonstrate that with adaptive slot allocation algorithms, it is possible to minimize such interference under low traffic loading conditions. The second contribution is to design a feedback-based adaptive allocation protocol that can minimize those interferences without relying on any global synchronization mechanism. In the second problem, we develop a routing solution Off-Network Control Processing (ONCP) for sensor networks. A tiered hybrid routing approach, consisting of ?coarse grain? server-based global routing, and distributed ?fine grain? local routing is proposed for achieving scalability by avoiding network-wide control message dissemination. We present the ONCP architectural concepts and analytically characterize its performance in relations to both flat and hierarchical routing architectures.« less
