The Internet of Things or ‘IoT’ described as a highly interconnected network of heterogeneous devices where all kinds of communications with any type of devices seem to be possible, preserving the location privacy of sensors always been a concern specifically in critical and strategic areas, Analyzing the traffic of the packets allow the eavesdropper to derive the location of sensitive, important nodes, and then the attacker can control or destroy these node, which can be a threat to the whole network. While investigating location privacy protocols we have noticed a tradeoff between location-privacy and energy consumption in which affecting the performance and lifetime of the network. In this paper, we proposed a secure strategy for preserving the privacy of the source node location with routing modification of energy-awareness load balancing (ELB) protocol with random path selection in multipath routing fashion to provide path diversity with best energy consumption, each packet is forwarded randomly in a different direction. In addition, to get maximum privacy protection we initialize pre-defined tunnels of M intermediate hops for hiding the original path of the packet, Therefore, protecting source node location from backtracing by the attackers.
