Performance Analysis of Enhanced Ad-Hoc on-Demand Distance Vector Routing Protocol in Smart Environment

MANETs have specific features that can satisfy the mobility and heterogeneous requirement of the smart environment. Smart applications need high Mobility, Bandwidth, Reliability and less Packet Loss and Delays; therefore, it is important to provide good Quality of Service (QoS) in such applications. So there is a dire need of identifying and exploring the relevant protocols that may be adapted for IoT enabled the smart environment. The routing protocols in smart environments are accountable for connectivity among nodes, fairness, quality of service, etc. Protocol & path selection is the main strategies to design any mobile network. The chosen protocol must have the best in term of data integrity and data delivery. Hence the analysis of the protocols become an essential step. This paper presents various securities and safety-related issues of MANET-IoT system, and also advocate the requirement of enhancing routing protocols in a smart environment. In this research, a new enhanced cache update technique is introduced in MANET protocol to make it enable for the upcoming smart environment. The enhanced algorithm helps to detect the malicious node and remove the stale route present in the network, no matter which traffic mode is used and in which direction nodes are moving. Cache is upgraded in such manner that all nodes in the way are notified about the misbehaving node and its adjacent neighbors’ nodes will not use misbehaving node while searching for the route. Here the analysis has been done taking a various number of nodes. Packet Delivery and Packet Lost are two key parameters taken for analysis purpose.
