We extend the probabilistic key-based approach for wireless sensor networks concerning the slow rekeying and path key reestablishment processes. By introducing a novel, energy efficient, distributed, and faster scheme, we attempt to replace the existing ordinary rekeying method of probabilistic key management scheme through a deterministic algorithm that works on both the base station and on each...
We describe an improved version of simple polling protocol employed in a wireless sensor network proposed. Although this simple wireless sensor network works efficiently, it is very limited in computing capability. Simple polling protocol works well in situation where every sensor node shares heavy traffic. However, when a few sensor nodes contribute to the traffic, most of the time slots allocated...
