Effective Routing in Mobile Ad-hoc Networks With Power and End-to-End Delay Optimization: Well Matched With Modern Digital IoT Technology

Introduction

In Mobile Ad hoc Networks(MANETs) group of wireless nodes are connected which are always in mobile state and are linked with each other through radio waves in the absence of any central access point. Every node functions not as a node, as well as a router which forward the packets to the nest hop towards destination. Adhoc networks are helpful in situations where temporary network connectivity is required in emergency cases or in rescue processes, disaster relief assignments and also in military applications. Designing power management routing protocols is very much necessary in multi-hop wireless mobile ad-hoc networks because individual node contains insufficient battery power. So it is difficult to provide more power to the nodes in the network or to recharge them as these are infrastructure less and are difficult to access. Again the nodes are mobile and the network topology changes frequently due to frequent node mobility.

In Emergency and relief operations MANETs are very useful because they can be created quickly as and when required without an existing infrastructure. Figure 1 Shows a MANET and Wireless Mobile Network. In military exercises, conferences and classroom meetings application of MANETs in also equally important. In all these cases there is high movement of nodes and compactness of the network increases giving rise to disturbance in transmission. Therefore design of effective routing protocols is essential to meet successful routing.Designing a sustainable Adhoc Network is a demanding issue as the energy-controlled nodes are ordinary to run independently for long periods. Communication over wireless media within time constrained is needed to permit real-time mobile applications such as interaction between mobile robots and inter-communication among mobile vehicles. A proper high-level communication method to connect independent domains is achieved through real-time event-based communication prototype which has been widely implemented in large distributed control systems. In this work the authors try to make an attempt to investigate different strategies of power management of mobile nodes and delay computation with careful observation on realtime applications. In Mobile Adhoc Networks (MANET) data transmission is very challenging as there is no dedicated infrastructure, so forwarding data from source to destination through a multi-hop communication is difficult due to frequent change in network topology. There are other constraints such as limited battery power of the nodes, high mobility rate of nodes, delay constraints, Qos requirements of multi cast and real time communication etc.The Objective of this paper is to make a comprehensive study on heterogeneous challenges faced by MANET, basically for dynamic routing purpose and present a report on novel proposals with technical mechanism used in them to meet such challenges. Objective and Feature of all the novel works are listed out here which opens better opportunity to work in new research areas in MANET in order to solve the practical challenges related to such a dynamic network.
