Low Latency Based Efficient Aggregation Scheduling in Multihop Wireless Sensor Network

Abstract

In the Wireless sensor network small size based and low power sensor nodes spreads over a complete geographical area which is connected to each other for performing or control the applications. Every application requires a control center which collects the aggregates data from all sensor nodes. Data aggregation is used for compress data and also for power saving which gives time efficient method for collect the data. Wireless interface is also the main reason for delay in wireless sensor network. In this paper, we present two delay efficient algorithms, CIAS(Compressive Improved Aggregation Scheduling Algorithm), CDAS(Compressive Distributed Aggregation Scheduling Algorithm). CIAS and CDAS will be able to reduce the delay for wireless sensor network which is introducing by wireless interface. CIAS and CDAS algorithms provide collision-free links for data aggregation. In the results, we prove that latency or delay for the proposed algorithms(CIAS / CDAS) is low as compare to DAS, IAS.
