Survey of Reliable Data Delivery for Highly Dynamic Mobile Ad Hoc Networks

摘要

Mobile Adhoc Network is a communications less and decentralized network which request a robust dynamic routing protocol. To provide the needs of communications for Mobile Ad hoc Network (MANET) many routing protocols have been proposed in earlier works. Routing is the challenging issues in Mobile Ad hoc Network (MANET). Most existing ad hoc routing protocols are susceptible to node mobility, especially for largescale networks. In Mobile Adhoc Network there is problem in delivering data packets for highly dynamic mobile ad hoc networks in a reliable and timely manner. In this paper we study the existing routing protocol approaches and address the problem of reliable data distribution in dynamic large scale mobile adhoc network. An efficient Positionbased Opportunistic Routing (POR) protocol is good in delivering the data in highly dynamic MANETs. But it is affected by the over heading problem and moreover there are no data confidentiality and data security. In order to minimize the black holes in the destination path and make more security, we study the various voidhandling approaches .In the case of communication hole a Virtual Destinationbased Void Handling (VDVH) schema find an efficient routing path with more security. The survey will helps to understand the problem of existing routing strategy for reliable data delivery and also be used to develop a new or to extend already proposed schemes in reliable and efficient manner.
