The lifetime of an ad-hoc network depends on a mobile device?s limited battery capacity. In ad-hoc multi-hop communication, source nodes use intermediate nodes as a relay to communicate with remote destinations. As cooperation between nodes is restrained by their battery resources, it might not be in their best interests to always accept relay requests. Therefore, if all nodes decide how much energy to spend for relaying, selfish or non-cooperative nodes reduce cooperation by rejecting to forward packets to others, thereby leading to a dramatic drop in the network?s throughput. Three strategies have been founded to solve this problem: tit-for-tat, live-and-let-live, and selective drop. This research explored a new strategy in ad-hoc cooperation which resulted from the combination of the live-and-let-live and selective drop strategies. This new strategy is based on the suggestion to select fewer hops with a low drop percentage and sufficient power to stay alive after forwarding the data packets towards the destination or other relays at the route path. We used a genetic algorithm (GA) to optimise the cooperative problem. Moreover, the fitness equation of the GA population was designed according to the mixing of the two strategies, which resulted in a new optimized hybrid dynamic-static cooperation.

Ad Hoc Network Communication is mobile networks communications and have a high mobility for each of its nodes. This type of network communications is a temporary networkwith utilizing a WiFi network or Bluethoot as a medium of communications. In the entirenetwork, node moves with a speed varying and unpredictable direction. Packets data delivery from the source node to destination node by using an ad hoc network requires its owntechniques. In this research discussed the existing data communication technique inVehicular Ad Hoc Network (VANETs) Communications with attention: Broadcasting Time, Routing Protocol, Message Dissemination, Delay Tolerant Network Dissemination and / DTN.These techniques can increase the delivery ratio / sending data packets to the destination as well as a smaller delay time. In order to maintain the integrity of the data packets received bythe destination node, the authors have proposed a method of duplicate messages in thisresearch.

Networking Technology

Recently, the flying ad-hoc network (FANETs) is a popular networking technology used to create a wireless network through unmanned aerial vehicles (UAVs). In this network, the UAV nodes work as intermediate nodes that communicate with each other to transmit data packets over the network, in the absence of fixed an infrastructure. Due to high mobility degree of UAV nodes, network formation and deformation among the UAVs are very frequent. Therefore, effective routing is a more challenging issue in FANETs. This paper presents performance evaluations and comparisons of the popular topology-based routing protocol namely AODV and position-based routing protocol, namely LAR for high speed mobility as well as a verity of the density of UAV nodes in the FANETs environment through NS-2 simulator. The extensive simulation results have shown that LAR gives better performance than AODV significantly in terms of the packet delivery ratio, normalized routing overhead, end-to-end delay, and average throughput, which make it a more effective routing protocol for the highly dynamic nature of FANETs.

Integrating the Mobile Ad-Hoc Network (MANET) with Internet has many advantages. The Data collected from the Mobile nodes can be broadcasted to the world by connecting the Internet to it via Gateway. Clustering is a practical way to enhance the system performance. Security is a significant issue in the Integrated MANETInternet climate in light of the fact that in this climate we need to think about the assaults on Internet availability. So, to overcome this issue, we have proposed Secure and Authenticated routing protocol (SARP) to enhance security performance of the networks. This routing protocol is used to discover a secure route and to transmit data packets securely. In this protocol clusters are formed and security relies on the hardness of the symmetric and asymmetric key algorithms. We show the practicality of this convention as for the security prerequisites and security investigation against different assaults. The estimations and reproductions are given to show the security of the proposed convention. The outcomes show that, the proposed convention have preferred execution over the current secure conventions for Cluster based Internet Integrated with MANETs, in terms of security.

Mobile Ad hoc Network is a decentralized network which can be deployed instantly. Routing is a very challenging task in this network due to dynamic movement of mobile nodes. Various routing protocols such as OLSR, DYMO and ZRP are proposed to establish the route for the data packets in MANET’s. As deploying of the protocols into real environment is a cost expensive process, the protocols are initially evaluated through a simulated arena. Many of the mobile devices are battery equipped and each protocol consumes energy in different manner. In this paper, energy consumption evaluation is carried out on OLSR, DYMO and ZRP protocols in a grid environment. The experiments have shown that DYMO protocol has less energy consumption when compared to OLSR and ZRP protocols.
