In the traffic system, the problem of congestion control is very common, and it is classically handled by the global positioning systems by the drivers as well as traffic administrative authorities. But as the traffic density is increasing day by day, it is becoming difficult to handle and view all the possibilities in the prospective traffic area where the driver is willing to move. Moreover, the problem of security and integrity is also increasing rapidly as there are number of attacks in VANET and GPS systems being used by the crackers by sending the malicious code or fake packets. Ubiquitous computing is one of the recent technologies that is in the phase of implementation under Internet of Things (IoT). In this research manuscript, the approach to integrate the dynamic key exchange with the Elephant Herd Optimization (EHO) is presented to achieve the higher degree of energy optimization and overall lifetime of the network communication. The key concept of the cluster head shuffling using EHO and inner modules of key exchange are simulated in Contiki-Cooja that is open source simulator for advance wireless networks. Keywords: Advance Wireless Networks, Energy Aware Wireless Networks, Power and Energy Optimized Wireless Systems. 1. Introduction The term Internet of Things was first presented by Kevin Ashton in year 1999. The implementation of IoT is widespread now because of the availability of high performance wireless technologies. Radio Frequency Identification (RFID) tags and Sensors are base in the implementation of IoT. The RFID tags can be embedded in real world devices and objects which can be monitored remotely using software based applications. The RFID readers can be used to locate, read and sense the RFID implanted objects. Very small micro sized transmitting and receiving chips are integrated with RFID which can communicate at distant point. As per the reports from Forbes.com, the market of Internet of Things will reach around 267 billion dollars by year 2020. The analysis from Gartner underlines that around 8.4 billion objects with investment of 273 billion dollars will be interconnected with each other in current year 2017. RPL (Routing Protocol over Low Power and Lossy Networks) RPL alludes to the Routing Protocol in view of IPv6 that is implied and concocted towards Low-Power and Lossy Networks. It is taken accepted routing layered convention for the Internet of Things (IoT). From its consistency, RPL added to the advancement of corre- spondences in the realm of small, inserted, organizing gadgets, by giving, alongside different measures, gauge engineering for IoT. Routing issues are exceptionally trying for 6LoWPAN, given the low-power and lossy radio-interfaces, the battery provided hubs, the multi-bounce work topologies, and the successive topology changes because of portability. Fruitful arrangements ought to con- sider the particular application necessities, alongside IPv6 conduct and 6LoWPAN systems. A compelling arrangement was created by the IETF Routing Over Low power and Lossy (ROLL) systems working gathering. It has proposed the main IPv6 Routing Protocol for Low power and Lossy Networks (LLNs), RPL, in light of an inclination based approach. Fig. 1: 6LowPAN Environment Fig. 2: Routing in RPL. Existing routes are shown next to the network nodes This problem can arise in RPL when there is inconsistency in the topology. Inconsistency arises due to the congestion, loss of packets or any node failure. RPL enables each node in the framework to pick if packets are to be sent upwards to their family or downwards
