AODV is a reactive MANET routing protocol that does not support security of routing messages. SAODV is an extension of the AODV routing protocol that is designed to fulfil security features of the routing messages. In this paper, we study the performance of both AODV and SAODV routing protocols under the presence of blackhole, grayhole, selfish and flooding attacks. We conclude that the perform...

Mobile ad hoc network (MANET) is characterized as a dynamic, multi-hop wireless self-organized distributed ad hoc network. Because of node mobility and power limitation, the network topology changes frequently which leads to path breakage. Hence a dynamic routing protocol is required for ad hoc networks to function properly. Reactive on -demand routing protocols becomes very popular because it ...

Mobile Ad-hoc Network (MANET) is a wireless network that comes with few routing protocols which have varied mechanisms. Studies show operations consume energy while current research focuses more on MANET protocol operation and its performance evaluation, the required for successful equally demands quality attention of researchers. Hence, need to expand scope study neglected area studies. To bri...

This paper aimed at the detection of wormhole attack and proposed a new method called as Neighbour Node Ratio Adhoc On demand Distance Vector Routing (NNR-AODV). NNR-AODV is an extended version traditional AODV routing protocol. The calculates neighbour node count for every based on that it will decide whether present or not. Furthermore, able to detect both external internal attacked nodes. Al...

Ad hoc On-Demand Distance Vector (AODV) Routing is a routing protocol for mobile ad hoc networks (MANETs) and other wireless ad-hoc networks. The traditional AODV protocol cannot address to multi rate PHY communications. In this project, we analyze the relationship between data rate, corresponding transmission range and number of hops in AODV protocol and find the optimal data rate for AODV con...

Wireless Body Area networks (WBANs) are a subset of wireless sensor networks that interconnect miniaturized nodes with sensor or actuator capabilities in, on, or around a human body. WBANs can operate over a number of different frequency bands such as MICS (Medical Implant Communications system), 2.4 GHz ISM (Industrial Scientific and Medical), UWB (Ultra Wideband), HBC (Human Body Communicatio...

Energy is an important characteristic of Mobile Ad hoc Network (MANET). We proposeanEnergy Aware Multipath AODV protocol (EAMAODV) based on AODV. EAMAODV obtains nodes energy by upgrading the route discovery and route maintenance process of AODV. It calculates drop rate derived by routes total hops. Drop threshold is used in deciding the route. Simulation is done using NS-2.35. The results show...

A Mobile Ad Hoc Network (MANET) is a dynamic wireless network that can be formed without the need for any pre-existing infrastructure in which each node can act as a router. Providing high quality communications service among mobile wireless devices is basically a challenging task in wireless ad hoc networks. This paper proposes a multipath routing protocol called entropy-based multipath AODV (...

This paper proposes a novel routing scheme for mobile ad hoc networks (MANETs), which combines the on-demand routing capability of Ad Hoc On-Demand Distance Vector (AODV) routing protocol with a distributed topology discovery mechanism using ant like mobile agents. AODV requires the actual communication to be delayed until the route is determined (found). This may not be suitable for real time ...
