There are two types of wireless networks, infrastructure wireless network and wireless Ad-hoc networks. Wireless Ad-hoc networks are well suited for use by emergency response teams, for search and rescue operations that require teambased communications in the absence of working telecommunications infrastructure, while infrastructure networks require the existence of access point in which all th...

A Mobile Ad hoc Network (MANET) is a self-configuring infrastructure less network of mobile devices connected by wireless. These are a kind of wireless Ad hoc Networks that usually has a routable networking environment on top of a Link Layer Ad hoc Network. The routing approach in MANET includes mainly three categories viz., Reactive Protocols, Proactive Protocols and Hybrid Protocols. These tr...

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...

Spontaneous networks lack an a priori communication infrastructure, the neighbors are unknown right after deployment, and they used during period of time in certain location. In this paper, we present new randomized creation model spontaneous wireless ad hoc network based on trusted neighbors. The idea is to manage neighbor discovery with exchange identity cards, checking signature establishes ...

Ad Hoc networks does not connected central mode. It is infrastructure less wireless network. Due to high mobility of nodes and multipath propogations topology of this network is dynamically changes. It is self configured network. No. of mobile nodes are connected internally in this network. Mobile Ad Hoc networks protocols are different from other internet protocols of infrastructure based wire...

Future wireless ad hoc networks will use mobile routers to provide Internet connectivity to mobile ad hoc users. A mobile router also allows mobility of an entire ad hoc network, e.g. in plains, trains, cars, and other vehicles, where mobile users may use an Internet access within an ad hoc network domain. Mobile Internet access is also required for various mobile networks such as Personal Area...

Wireless Ad Hoc Networks is a special kind of wireless communication network. With the great development of multimedia applications, how to provide QoS guarantee in the MAC layer is the hot topic in wireless ad hoc network (MANET). This paper designed a QoS model in MANET. The feasibility and reliability of this model is analyzed and verified. Compared with the traditional model, the proposed a...

An ad hoc network is a collection of mobile nodes using wireless network interfaces to communicate among themselves, discovering and routing along possibly multihop routes to each other without the assistance of fixed infrastructure. In this paper, we describe the design and demonstration of a set of simple routing protocol mechanisms that substantially improve the transmission of real-time mul...
