A Mobile Ad hoc Network (MANET) is a mobile wireless network composed of several mobile nodes that communicate among themselves without the intervention of any centralized management or existing infrastructure. Hence, these mobile nodes must necessarily be able to cooperate to allow communication between them. MANETs have vast applications in the areas of personal area networking and other common areas. There are also existing and future military networking requirements for robust, IP-compliant data services within mobile wireless communication networks. Routing in MANETs is a particularly challenging task because the topology of the network changes dynamically, the bandwidth of the wireless medium is limited, the medium is shared and it lacks central control or infrastructure in the network. Adaptability is therefore, an important factor in MANETs. Hence, the present work has experimented with the bio-inspired protocols which are inherently adaptive in nature. Motivations to investigate bio-inspired routing are the following: No topology update is needed and the latency for route determination is zero. AntHocNet is one such protocol which is chosen to conduct the experiments. AntHocNet has been designed after the Ant Colony Optimization framework and its general architecture shares strong similarities with the architectures of typical ACO implementations for network routing. Using a substantial set of simulation experiments in ns-2, we have compared and analyzed the performance of the AntHocNet algorithm with the traditional AODV algorithm. The metrics used for performance evaluation: Energy consumption, convergence time, average end to end delay, throughput and overall network lifetime etc. It is observed that the bio-inspired adaptive hybrid routing protocol has outperformed the traditional routing protocol AODV on the different performance evaluation metrics while changing the parameter like density of nodes and pause time.
