A mobile ad hoc network is networks which utilizes multi-hop radio relaying and are capable of operating without the support of any fixed infrastructure. Efficient dynamic routing is a challenge in such a network. On-demand routing protocol is widely developed in ad hoc networks because of its effectiveness and efficiency. In this paper, the significance of Ad hoc On-Demand Distance Vector (AOD...

In this work, we present the design of a mitigation scheme for jamming attacks integrated to the routing protocols MPH, AODV, and DSR. The resulting protocols are named MPH-M (Multi-Parent Hierarchical - Modified), AODV-M (Ad hoc On Demand Distance Vector - Modified), and DSR-M (Dynamic Source Routing - Modified). For the mitigation algorithm, if the detection algorithm running locally in each ...

Problem statement: Wireless Mesh Networks (WMNs) is an emerging technology for wireless environment. Since WMNs are permanent or semi-permanent network, an efficient and reliable path establishment is the core concern for such type of networks. Several performance metrics has been designed for WMNs such as Expected Transmission Count (ETX), Expected Transmission Time (ETT), interference Aware R...

Mobile ad hoc network (MANET) is a standalone network capable of autonomous operation where nodes communicate with each other without the need of any existing infrastructure. Mobile ad hoc networks consist of nodes that cooperate to provide connectivity and are free to move and organize randomly. Every node is router or an end host, in general autonomous and should be capable of routing traffic...

A mobile ad hoc network (MANET) [1] consists of a set of mobile hosts capable of communicating with each other without the assistance of base stations. The topology of ad-hoc networks changes rapidly. The Ad hoc On Demand Distance Vector (AODV) [2] routing protocol and other ondemand routing protocols suffers with many problems like delay and packet loss caused due to link break, time required ...

MANETs are very advantageous and fruitful when there is no infrastructure or has been destroyed due to some reasons like earthquake, floods and so on. Data communication in MANETs are very challenging issue due to threats like limited battery power, limited bandwidth, mobility, routing and QoS and so on. Due to these challenges and scarcity of resources in MANETs, it’s very difficult to achieve...

Routing is a challenging issue in Mobile Ad hoc Network to pass the data packets through intermediate hops in an efficient manner. In this paper, Reactive routing protocols namely AODV and DSR are evaluated under the feasible placement and random placement models. Simulation results shows that AODV and DSR are performing better in feasible placement approach comparative to the existing random p...
