Quality of Service (QoS) provisioning and management in ad hoc networks remains a challenging task. Existing research focuses either on providing QoS or on network management, in ad hoc networks. However, a comprehensive approach to QoS management in ad hoc networks, i.e. network management in support of service differentiation, QoS robustness, and network survivability is still lacking. In thi...

A mobile ad-hoc network is an autonomous collection of mobile nodes that communicate over bandwidth constrained wireless links. Due to nodal mobility, the network topology may change rapidly and unpredictably over time. The routing protocols meant for wired network cannot be used for mobile ad-hoc network because of mobility of network. A number of routing protocols like Destination-Sequenced D...

Ad hoc networks are special networks that do not require an infrastructure. Nodes of such networks are usually mobile and wireless. Wireless nodes use a shared medium for communication, so they are able to communicate with many nodes directly provided they are within communication range of those nodes. In this article we present a study of secure ad hoc routing protocols for wireless Networks. ...

A mobile ad hoc network is a collection of mobile wireless nodes that can dynamically form a network without necessarily using any pre-existing network infrastructure. In general, routes between nodes in an ad hoc network may include multiple hops. Due to the potential ease of deployment, many practical applications have been conceived for ad hoc networks, including personal area networking, ho...

The development of ubiquitous computing and mobility opens challenges for implementation of grid computing in ad hoc network environments. In this paper, a new grid computing implementation for ad hoc networks is proposed. The proposed addition of the ad hoc network protocols suite offers an easy and effective way to exploit the computing power of the network nodes. The model is implemented in ...

Wireless sensor ad-hoc network usually applied in a monitoring system like monitoring temperature, humidity or even any triggering inputs from a connected peripheral device. The approach of wireless ad hoc network for monitoring video data is under preliminary investigation and development because video streaming requires larger storage, quality channel, less jittering and low packet loss. The ...

Mobile Ad hoc Networks (MANET) is a part of wireless networks. No wires and fixed routers are used in this type of network. It is not everlasting network; it is the short term network. Nodes has the capability to self organize themselves and it follows infrastructure less architecture. Network is formed by number of nodes moving in an inconsistent manner. They do not form any topology. Few exam...

A mobile ad hoc network is comprised of mobile hosts that can communicate with each other using wireless links. It is also possible to have access to some host in a fixed infrastructure depending on the kind of the mobile ad hoc network. Mobile ad hoc networks can be realized by different networks such as body area network (BAN), vehicular ad hoc network (VANET), wireless sensor network (WSN). ...

There is still no consistent definition of general ad hoc network properties. All introduced protocols for ad hoc networks are based on different assumptions and security requirements, and are consequently suited for specific applications only. Due to the broad field of applications, a general security model can still not be found in any literature. We define two ad hoc network categories, name...

Energy optimization is the main requirements of wireless ad-hoc network that consumes less energy to give optimum performance under limited bandwidth and low battery power of each node. Network life time is the main issues in ad-hoc network. In this paper, first investigate and analyze the impact of receiving energy on nodes remaining energy in networks. Analysis and simulation results show tha...
