IEGGR: Improved Energy-aware and Delivery Guarantee Geographic Routing

Wireless Sensor Networks are a set of sensor nodes that probe their surroundings and send data over multi-hop routes to base-station (BS) for processing. Many routing protocols have been developed WSNs. A great attention has given geographic protocols, which rely only on local knowledge disseminate towards the BS. In this paper, we propose new energy efficient protocol called Improved Energy-aware delivery Guarantee Geographic Routing (IEGGR). The proposed exploits positions neighboring nodes, closest BS forward packets through shortest path in terms consumption. IEGGR introduces mechanism order efficiently around voids. algorithm considers WSN as connected-graph route packet from source node BS, tries making locally optimal choice at each intermediate with hope finding global optimum path, aims minimize To find greedily forwarding its neighbor iteratively building end-to-end path.
