Wireless sensor networks are useful in various industrial, commercial, Internet of Things (IoT), Internet of Everything (IoE) and many important tracking purpose applications. Energy is a limited and not replaceable. Hence it is the most focused research area in the field of wireless sensor networks. In this paper, Cluster Based Energy Resource Efficient & Next Hop Knowledge based Routing Protocol (CBERERP) is proposed for multiple heterogeneous wireless sensor networks. For any routing protocol, energy resources generally depend on number of message exchanges, transmission of data and control packets among the various sensor nodes to reach an agreement. CBERERP uses distributed concept for selection of cluster head among of heterogeneous nodes and intelligent cluster formation to minimize the energy consumption. Further, the proposed protocol reduces energy using a routing technique which minimizes the hop distance, the number of transmission of data and the number of control packets.
Abstract-Advancement in wireless technologies allows mobile devices to access Internet from anywhere at any time.Each network is identified by unique IP address. Mobile IP allows a mobile node to change its network without changing IP address. Internet Engineering Task Force (IETF) has suggested several mobility management protocols such MIPv6, HMIPv6, PMIPv6 etc. for perpetual mobility. MIPv6 is a Host-Based Mobility Management (HBMM) protocol and provides global mobility solution to the mobile node. MIPv6 suffers from basic mobility related problems such as handover latency, packet loss etc. Recently the IETF has suggested Network-Based Mobility Management (NBMM) protocol. The Proxy Mobile IPv6 (PMIPv6) is first NBMM protocol. PMIPv6 significantly decreases the signaling overhead, but still has some issues related to the security, handover latency and packet loss. This paper proposes Secure and an Optimized Authentication Scheme in PMIPv6 (SOAS-PMIPv6) to reduce signaling overhead. The proposed scheme provides higher security than the basic PMIPv6 protocol and moreover reduces the signaling cost with respect to contemporary protocols. This paper performs comprehensive analysis on handover latency, packet delivery cost, packet loss etc. and the performance of protocols is mathematically investigated. Numerical result shows that the proposed scheme has improved performance than the MIPv6 in terms of handover latency and provides optimized security than PMIPv6 based protocols.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
