A hstractMobile ad hoc networks have attracted attention lately as a means of providing continuous network connectivity to mobile computing devires, regardless of physical location. To date, a large amount of research has focused on the routing protocols needed in such an environment. In this paper, we investigate the effects that the routing and link layers have on TCP performance. In particul...

Routing (and forwarding) is a core problem in networks for delivering data from one node to another. Today wireless networks are becoming popular because of their “3 Anys”– Any person, Anywhere and Any time. Wireless ad hoc networks are termed as mobile distributed multihop wireless networks without predetermined topology (preexisting fixed infrastructure) or central control. In this paper, we ...

Routing is a core problem in networks for delivering data from one node to another. Wireless Ad Hoc networks are also called Mobile Ad Hoc multihop wireless networks without predetermined topology or central control. In this paper I present a number of ways of classification or categorization of these routing protocols and did Qualitative / Quantitative analysis of a dozen typical existing rout...

In this paper, we propose an extension to existing power control (PC) management algorithm in a multihop wireless ad hoc network. Typical power control assumes that mobile nodes communicate with each other by one-to-one. However, one-to-many style communication is necessary for energy-efficient communications of several applications where broadcast or multicast is used. In this paper, we identi...

Mobile Ad Hoc networks are autonomous, infrastructureless networks that support multihop communication through IP routing. This paper examines the use of Mobile IP in order to provide global Internet connectivity to ad hoc networks that use an on-demand routing protocol. We present a hybrid scheme that uses techniques such as TTL scoping of agent advertisements, eavesdropping and caching agent ...

An ad-hoc network is a collection of wireless mobile nodes that forms a temporary network without any centralized administration. While early research effort assumed a friendly and cooperative environment and focused on problems such as wireless channel access and multihop routing, security has become a primary concern in order to provide protected communication between nodes in a potentially h...

Ahoy, a protocol to perform local service discovery in ad-hoc networks is described in this paper. The protocol has been implemented in a discreteevent simulator to study its performance in case of a multihop mobile ad-hoc network. Especially the effect of mobility on the network load and the probability of finding services is investigated. Experiments show that the load caused by advertisement...

For wireless ad hoc networks with multihop transmissions and Rayleigh fading, this paper maximizes the overall system throughput subject to QoS constraints on power, probability of outage, and data rates. Formulations are also given which minimize delay and optimize network resources in a wireless ad hoc network, where each link is shared by multiple streams of traffic from different QoS classe...
