A Real-Time Routing Protocol along with new Reliability Approach in Wireless Sensor Network

Reliable and real-time packet transmissions along with minimum energy consumption are main challenges in designing routing protocols to realize many applications of Wireless Sensor Networks (WSNs). With considering these challenges, we proposed a novel Geographical Reliable and Real-time routing Protocol (GRRP) which takes energy consumption into account. This protocol is based on two new approaches called geographical area divisions and efficient node selection function. GRRP makes use of these approaches to determine the best geographical angle and optimum nodes in the angle. In order to hit its goals, GRRP utilizes a novel multi-path routing algorithm. As the simulation results indicate, GRRP outperforms state-of-the-art protocols in terms of average end-to-end delay, throughput and reliability.
