Performance Evaluation of Ad-Hoc Networks in Static & Mobile Environment

The Internet Protocol version 6 (IPv6) based routing protocol for low power and lossy networks (RPL) is used for routing in the static networks such as wireless sensor networks (WSNs) and internet of things (IoT). The research is going on to implement the RPL for mobile networks like vehicular ad-hoc network (VANET) and mobile ad-hoc network (MANET). These networks are infrastructure less and self-configuration is required to connect these mobile devices. There are some limitations of the RPL when the network is dense and mobility is introduced in it. For the solution of this problem, this paper presents the performance evaluation of RPL in the mobile network and comparison is performed with the static network. The implementation is done on the Contiki environment and results are analyzed on Cooja (network simulator). It is observed that the RPL performance depends strongly on number of sender nodes, sink nodes, and also on the inclusion of mobility to the nodes. The metric values increase with more packet loss with increasing the number of nodes in the network. Further the increase in number of sink nodes provides lesser packet loss, retransmission, and the energy consumption. The introduced mobility increases the network energy consumption.
