PRIORITIZING SENSED DATA TRANSMISSION BY CONSENSUS RELATION IN WIRELESS SENSOR NETWORK

摘要

In this work we propose an approach to prioritizing order of transmission of sensed data in wireless sensor network that are very popular in, for example, environmental monitoring. The approach is based on determination of a consensus relation which is in "nearest distance" from all initial rankings shaped by multiple sensors of each network node. Statistically and probabilistically based analytical models useful for assuring network performance and providing reasonable number values n - k and m are proposed and discussed, where n - k is a number of packets transmitted to the sink; n is a number of the network sensor nodes; k is a number of dropped packets due to a congestion; and m is a number of node sensors (or rankings).
