A new approach for a better recovery of cluster head nodes in underwater sensor networks

Abstract

Energy efficiency is an important issue during the design and the overall performance evaluation of an UWSN system. Clustering sensor nodes have proven to be an effective method to improve the load balancing and scalability of the network while minimizing the system's overall energy consumption. In this paper, a new clustering algorithm is proposed to provide an improved cluster system against clusterhead failures. This study suggests that system CH failures could be further minimized when simultaneously a CH (primary CH) and a vice/backup CH are selected. Thus, when a primary CH fails due to an irreparable fault, a backup CH will take its place and it will operates as a head node. This study proposes two major procedures in order this to be accomplished, the detection failure and the recovery procedures. The first one initially detects any failures that occurred in the network and then reports this information to the relevant nodes to initiate recovery. The recovery procedure actually decides who and when will trigger the recovery function according to the origin of the CH node failure which can be either the energy depletion of the CH's battery or a software/hardware malfunction. The simulation results clearly indicate that there is an improvement in terms of network lifetime expectancy and energy consumption.

A novel fault detection and recovery technique for cluster‐based underwater wireless sensor networks

“…We compare the energy‐efficient adaptive hierarchical and robust architecture (EDETA), recovery of CH (RCH), and self‐deployment for maximized coverage and guaranteed connectivity (SDMCGC) protocols with our proposed FDRT protocol. On the basis of the above‐mentioned performance metrics, the simulation results are presented below.…”

“…The scheme has introduced the role of substitute node as CH on its failure. Ovaliadis et al have proposed an effective clustering mechanism to provide a more efficient cluster structure against cluster‐head failures in underwater sensor network by selecting BCH in the place of primary CH. Both schemes have discussed the alternative of failed CH but ignored the CM failure.…”

Survey of Connectivity Restoration in 3D Wireless Ad Hoc/Sensor Networks

“…The articles [18,19] are cluster-based recovery algorithms, and both of use cluster head and candidate cluster head methods for recovery. The article [18] proposed a new fault detection and recovery technology (FDRT) for underwater wireless sensor networks based on clusters.…”

“…The article [19] also proposed a new method to better restore cluster head nodes in underwater sensor networks. This paper also adopted the method of primary cluster head (CH) and standby cluster head (BCH) and realized this through two main programs, namely, detection failure and recovery program.…”

“…It requires the deployment of many nodes in advance, leading to resource wastage. [18,19] Active fault detection, node movement recovery based on clustering using cluster head and candidate cluster head methods Their algorithms all reduce the energy consumption and extend the network life.…”
