A Survey on Reliability in Wireless Sensor Network

Objectives: This study was conducted to identify Quality of Service parameters used in network. Different reliability types and performance metrics needed to predict reliability in wireless sensor network. Methods/Analysis: Sectoring scheme can be used for partitioning of network into different sectors. This scheme is used to improve reliability in wireless sensor network. Findings: In existing method various clustering algorithms are used for partitioning of network. Clustering consists of position of cluster head and if it far away from the sink in large network, the cluster node utilizes more energy. Therefore, for WSNs, it is especially vital to intend an algorithm to divide sensors in sectors to maximize the reliability (packet) and minimize the energy consumption apply for transformation of information from the sensor nodes to the base station i.e., sink node. Application/Improvement: Sectoring scheme is unique method used to acquire more packet delivery ratio i.e., the reliability of a sensor based network. To achieve reliability, different factors need to be considered for network review like number of sectors, angle between two sectors, packet size, node density, MAC protocols and Routing protocols.
