In one hand, sensor nodes consume low energy when they communicate with TDMA protocol, by eliminating collisions and idle listening. On the other hand, data aggregation algorithms are used to gather and aggregate data in an energy efficient manner so that network lifetime is enhanced. TDMA protocols are more power efficient since nodes in the network can enter inactive state until slot times will...
SPEED routing algorithm is a service quality based algorithm in which data aggregation dose not happen. In this article, data aggregation has been added to the conventional technique in SPEED algorithm. The idea involves virtual configuration of sensors and specification of an individual ID to the created data by the sensors in each region, then data aggregation in relay node is done by this ID, resulting...
