Mobile ad hoc networks are designed to work in environments, where the terrains have unpredictable obstacles such as hills, water bodies, buildings or regions without any nodes. In the mobile ad hoc network, the mobile nodes use the directional antennas to achieve high spatial reuse. If the nodes with the directional beam move, then the obstacles may come between the communicating nodes. The link quality deteriorates resulting in link break, causing disruption in the communication. This paper proposes a scheme, which allows the mobile nodes to maintain the link in an irregular terrain by dynamically changing antenna mode from directional to omni. The proposed model has been simulated using Qualnet simulator (version 4.5). The simulation results shown that the proposed model is improved the network performance in terms of packet delivery ratio, number of link breaks and number of hops.

Wireless ad hoc networks are growing important because of their mobility, versatility, and ability to work with fewer infrastructures. The mobile ad hoc network is an autonomous system consisting of mobile nodes connected with wireless links. Establishing a path between two nodes is a complex task in wireless networks. It is still more complex in the wireless mobile ad hoc network because every node is no longer as an end node and an intermediate node. In this paper, it focuses on design of connectionless routing protocol for the wireless ad hoc networks based on the mobile agent concept. The proposed model tries to discover the best path taking into consideration some concerns like bandwidth, reliability, and congestion of the link. The proposed model has been simulated and tested under various wireless ad hoc network environments with the help of a different number of nodes. The results demonstrate that the proposed model is more feasible for providing reliable paths between the source and destination with the minimum control message packets over the network. It has delivered more number of packets to the destination over the network. Copyright

Vehicular delay tolerant networks (VDTNs) suffer due to insufficient connection opportunities in sparse infrastructure. The sparsity of the network results in poor delivery ratio (DR). Deployment of additional small nodes named throwbox increases the contact opportunities, resulting in improved performance in terms of DR. However, randomly deployed throwboxes do not provide optimum results. Therefore, this article proposes the throwbox deployment as an optimization problem. Customized binary particle swarm optimization-based optimization method is employed to solve the problem. With the objective of maximizing the DR, the method optimize the placement of k-throwboxes in the network. The performance of the proposed methods is tested and compared by simulating a VDTN model in opportunistic network environment simulator. The optimization framework was implemented in Matlab. Exhaustive experiments were carried out by varying the number of throwboxes (k). A statistical comparison of the results with the existing throwbox deployment methods validates the effectiveness of the proposed optimization-based approach. The article also presents an analysis for choice of value of k for a desired network performance.
