Real Time Routing Protocol Based on Data Driven Link Estimation in Sensor Networks
Shen Xue-ping · 2010
In this paper,a real-time routing protocol based on data-driven link estimation for wireless sensor networks was presented.This protocol relies on the location information,constructs the next hop nodes set by forwarding path distance vector,combines the data-driven idea to form velocity vector with delay,delivery rate and single hop distance,and provide the soft real time of end to end data.Real time and energy consumption are the primary evaluation target for this protocol.With the ns2 simulation platform,the delay of this protocol reduces above 50% regard as AODV and DSR under the data rate 50 packets per second,energy consumption under 30%.This protocol can effectively improve the realtime performance and reduce network energy consumption.
