The route recovery algorithm is a crucial part of an ad hoc routing protocol. Designing an efficient and fast route recovery mechanism scheme without incurring extra overheads or delays to repair the broken link is a desirable goal for any routing protocol. The route recovery algorithm in reactive routing protocols like AODV occurs only after a link failure is detected. However, we propose a new route...
In this paper we consider the selection and deployment of MANET protocol to efficiently route the traffic and communicate in Tactical Battle Area (TBA). Tactical Wireless Communication Network (TWCN) provides connectivity between Wide Area System (WAS) of TWCN nodes, forming a backbone transmission network. TWCN is for TBA that consists of Network Centric Systems. These entities impose routing challenges...
Indeed, MANET's are an emerging technology, evolved to provide users with facility to establish Ad-hoc networks for seamless communication. Routing is a major issue in MANET's. AODV is considered as one of most efficient routing protocol in MANET's but, its performance is adversely effected by various security attacks. A routing protocol can be attacked in many ways so as to disrupt the routing process...
Secure routing in the field of mobile ad hoc network (MANET) is one of the most flourishing areas of research. Devising a trustworthy security protocol for ad hoc routing is a challenging task due to the unique network characteristics such as lack of central authority, rapid node mobility, frequent topology changes, insecure operational environment, and confined availability of resources. Due to low...
Wireless nodes in MANET present stringent resource constraints such as limited battery power and storage capacity, so energy aware cross-layer design is essential to improve the battery life. For prolonged network operational time, energy conservation is a critical issue in routing protocol design in ad-hoc wireless networks. Regardless of the energy saving issues, the conventional AODV routing protocol...
Developing with the node communication ability, the demand of ad-hoc networking has been turned from the terrestrial nodes to the air vehicles. In this paper, we discuss the composition of the communication system that can satisfy ad hoc network which node in this network has high speed (more than 100m/s), and long distance (10km-40km) to each other. Since the project is used in reality, the system...
MANETs is collection of wireless network establishing a network in which nodes communicate with each other by network systems such as the Internet. MANETs routing protocols are characterized into two types, for example, table-driven and on-request or demand. In this network node performed as a function of routers which discovers and maintain the path to other node. In Adhoc network nodes are easily...
Many MANET routing protocols do not perform well in dense scenarios with high network load. In these situations, we can observe a high level of route instability, which is often called "route flapping". In this paper we present the PRIME routing protocol, which uses a probabilistic multipath forwarding process to increase route stability in dense scenarios with high network load. We describe...
SatSim was developed to provide a low cost, easy to learn, network simulator for simulating satellite networks. SatSim is unique in that it accurately accounts for orbital movement of satellites on a discrete per packet basis that heavily affects communication link quality. SatSim can be seen as a special case of a typical network simulator, developed for networks that require physical node movement...
In mobile ad-hoc networks (MANETs), nodes use hello messages to detect neighbor nodes and to maintain link connectivity. In a typical MANET routing, a node broadcasts hello messages at a fixed interval. However, a fixed hello interval causes a long delay of neighbor discovery (too long hello intervals) or a more bandwidth waste by unnecessary protocol overhead (too short hello intervals). In this...
Rapid advancement in ad hoc networks and its variants, create a need for efficient and accurate routing decisions. As routing decisions for Mobile Ad hoc Networks has great impact on the overall performance of the network Quality of Service (QoS) parameters (delay, bandwidth, PDR etc.), optimized routing protocols need to be designed. One of the biggest challenges in designing ad hoc routing protocols...
MANETs are self-configuring, self-healing, and self-optimized network of devices which are mobile in nature connected by a wireless medium. All mobile nodes in “MANET” are mobile and therefore the nodes change their links with other devices very frequently. Some receiving nodes in the network maybe moved out-of-range of the sender node, therefore the data packets hops through intermediate nodes. The...
Science of networking is still a relatively immature area. Proposing an efficient dynamic routing protocol for MANET is an arduous and provoking task. Various protocols for routing phenomenon have been proposed to IETF [1]. Considering an ad-hoc network which is specified by frequently changing topology and infrastructure less connectivity, a protocol must be tested under realistic conditions but...
Due to high mobility of nodes, the major challenge of mobile ad hoc networks (MANETs) is the frequent link breakages which lead to numerous path failures and route discoveries. This paper introduces a novel signal strength based algorithm for RREQs forwarding (SAODV) to better exploit the neighbor coverage knowledge and hence reduce routing overhead in MANETs. The simulation results confirm the efficiency...
The mobile Ad-hoc network is an open wireless environment in which nodes are free to move anywhere without any topology and fixed infrastructure. Due to its open nature, it is vulnerable to various security attacks. There is a different kind of Denial of Service (DoS) attack such as Gray Hole attack drops fully or partially packets passing through them. Gray hole node able to change its behavior malicious...
The self-organizing wireless Mobile Ad-hoc Networks are characterized by the routing protocols they employ and the wireless technology used by the nodes in those networks. Process of route formation in MANETs is based only on the decision of network layer; resulting in network prone to congestion and degraded performance. Constraints imposed by MAC sub-layer and PHY layer go unnoticed with conventional...
Mobile Ad-hoc Network (MANET) is decentralized infrastructure less wireless network with self configuring dynamic nodes. Routing functionality is carried by nodes with the help of routing protocols for effective communication among them. Since routing protocols are major player in network, the intruders target these protocols. One such repudiation attack is Flooding attack. In flooding attack, malicious...
Adhoc networking field has been interestingly accepted by the research society due to its surprising features. Almost every aspect of the network has been explored by the researchers at some level of detail. A lot of analyses/ surveys have been presented in the literature for showing the performance of well accepted adhoc routing protocols viz. AODV, DSR, AOMDV, CBRP etc. This paper presents some...
As per need of recent applications, new research aspects related to scalability, heterogeneity, and power consumption have been emerged. These issues are supposed to be fixed for better utilization of MANETs. MANET nodes interact through multi-hop routing. AODV is a commonly used on-demand protocol for routing in MANETs. In the existing literature, AODV has been analyzed a number of times but heterogeneity...
