Devices for Wireless Sensor Networks (WSN) are limited by power and
thus routing protocols should be designed with this constrain in mind. This paper presents
and evaluates an Energy Efficient Position Based Adaptive Real-Time Routing
protocol (EFPBARP) as a novel, real-time, position based and energy efficient routing
protocol. EFPBARP is a lightweight protocol that reduces the number of nodes which
receive the RF signal using a novel Parent Forwarding Region (PFR) algorithm.
EFPBARP as a Geographical Routing Protocol (GRP) reduces the number of forwarding nodes and
thus the traffic and packet collision in the network. A series of performance evaluations through
Matlab and Omnet++ simulations show significant improvements in network performance parameters
and total energy consumption over CTP and Directed Flooding Routing Protocol (DFRP).
Keywords: CTP, DFRP, EFPBARP, GRP, VNP.
