Chicken Swarm Optimization

Wireless devices utilization had increased drastically, which has shown an impact on over-all demand and utilization Mobile Ad-Hoc Network (MANET). Routing protocol is the fundamental and vital performance factor in the Mobile Ad-hoc Network (MANET). The routing protocols in MANET are accomplished to handle a lot number of nodes with restricted resources. Multiple routing protocols exist in MANETs. Once of the main challenges in routing protocols is its generation of adverse influence on network performance. Accordingly, this paper plans to implement an obstacle-ware MANET routing model using improved meta-heuristic-based A* algorithm. The algorithm efficiently plots a path between multiple nodes avoiding obstacles, or points, on the graph that results in producing a shortest path without any obstacles. The improved meta-heuristic algorithm termed as Fitness and Position Ratiobased Chicken Swarm Optimization (FPR-CSO) is used to improvise the A* algorithm. The comparative analysis of different optimized A* over Ad hoc On-Demand Distance Vector (AODV) confirms the consistent performance of the proposed model

Since there is no infrastructure in mobile ad hoc networks, each node must rely on other nodes for cooperation in routing and forwarding packets to the destination. Intermediate nodes might agree to forward the packets but actually drop or modify them because they are misbehaving. The simulations in show that only a few misbehaving nodes can degrade the performance of the entire system. There are several proposed techniques and protocols to detect such misbehavior in order to avoid those nodes, and some schemes also propose punishment as well. It is very difficult to design once-for-all intrusion detection techniques. Instead, an incremental enhancement strategy may be more feasible. A secure protocol should at least include mechanisms against known attack types. In addition, it should provide a scheme to easily add new security features in the future. Due to the importance of MANET routing protocols, we focus on the detection of attacks targeted at MANET routing protocols This include WatchDog and Pathrater approach. A watchdog identifies the misbehaving nodes by eavesdropping on the transmission of the next hop. A path rater then helps to find the routes that do not contain those nodes. In DSR, the routing information is defined at the source node. This routing information is passed together with the message through intermediate nodes until it reaches the destination.

Hoc Networks

Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile hosts forming a temporary network without the aid of any stand-alone infrastructure or centralized administration. Due to the mobility of the nodes in the network, these nodes are self-organizing and self-configuring. Not only they act as hosts, but also, they function as routers. In MANETs, routing protocols are necessary to find specific paths between the source and the destination. The primary goal of any ad-hoc network routing protocol is to meet the challenges of the dynamically changing topology. Therefore, an efficient route between any two nodes with minimum routing overhead and bandwidth consumption should be established. The design of these routing protocols is challenging due to the mobility and the dynamic nature of the mobile ad-hoc networks. MANET routing protocols are categorized into two types: proactive and reactive. In this paper, the MANET characteristics and challenges are highlighted. Moreover, a comparison is conducted between three protocols: namely, DSDV, DSR and AODV in terms of both properties and performance.

Hoc Networks

Mobile ad hoc network is a type of ad hoc wireless networks which has become highly important in wireless communication. This network has composed of a set of wireless nodes and mobile phones and computer can play role of these nodes. Routing in these networks is complex and difficult because there is no fixed topology and nodes are freely displaced. In these networks, each node plays role of a router. Military networks, crime management networks etc. can be among the examples of mobile ad hoc network. One of the most important issues in ad hoc networks is routing. There are different types of routing protocols such as AODV and DSDV routing protocols. This report analyses and evaluates these two protocols with fuzzy logic and NS-2 simulator. This report is organized as follows: previous works, relates to concepts mentioned in this paper, the designed fuzzy system, results of simulation are mentioned.

Mobile Ad hoc Network (MANET) is an infrastructure fewer networks built on a multihop conveying idea. It transmits data from base node to end node. Because MANETS don’t have any fixed infrastructure and it works in a distributed manner. For efficient communication, many routing protocols are used in MANET. Routing protocols are to find a new route to transmit data from base to accurate end through the midway nodes. Every in-between node is act as a router. So, this paper is covers the routing protocols AODV, DSR, DSDV and OLSR to keep current routing information from every node to each other nodes. The purpose of this paper to offers a relative study of routing protocols in MANET and energy aware performance metrics are analyzed on two routing protocols of AODV and DSDV.
