AR-RBFS: Aware-Routing Protocol Based on Recursive Best-First Search Algorithm for Wireless Sensor Networks

Energy issue is one of the most important problems in wireless sensor networks. they consist of low-power sensor nodes and a few base station nodes. they must be adaptive and efficient in data transmission to sink in various areas. this paper proposes an aware-routing protocol based on clustering and recursive search approaches. the paper focuses on the energy efficiency issue with various measures such as prolonging network lifetime along with reducing energy consumption in the sensor nodes and increasing the system reliability. our proposed protocol consists of two phases. in the first phase (network development phase),the sensors are placed into virtual layers. the second phase (data transmission) is related to routes discovery and data transferring so it is based on virtual-based classic-rbfs algorithm in the lake of energy problem environments but,in the nonchargeable environments,all nodes in each layer can be modeled as a random graph and then begin to be managed by the duty cycle method. additionally,the protocol uses new topology control,data aggregation,and sleep/wake-up schemas for energy saving in the network. the simulation results show that the proposed protocol is optimal in the network lifetime and packet delivery parameters according to the present protocols. � 2016 farzad kiani.
