Courtesy piggybacking: Supporting differentiated services in multiop mobile ad hoc networks

by Wei Liu, Student Member, Xiang Chen, Student Member, Yuguang Fang, Senior Member, John M. Shea - IEEE Transactions on Mobile Computing , 2004
"... Abstract—Due to the salient characteristics such as the time-varying and error-prone wireless links, the dynamic and limited bandwidth, the time-varying traffic pattern and user locations, and the energy constraints, it is a challenging task to efficiently support heterogeneous traffic with differen ..."

with different quality of service (QoS) requirements in multihop mobile ad hoc networks. In the last few years, many channel-dependent mechanisms are proposed to address this issue based on the cross-layer design philosophy. However, a lot of problems remain before more efficient solutions are found. One

Securing ad hoc networks

by Lidong Zhou, Zygmunt J. Haas
"... Ad hoc networks are a new wireless networking paradigm for mobile hosts. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. Instead, hosts rely on each other to keep the network connected. The military tactical and other security-sensitive operation ..."

Mobility increases the capacity of ad-hoc wireless networks

by Matthias Grossglauser, David Tse - IEEE/ACM TRANSACTIONS ON NETWORKING , 2002
"... The capacity of ad-hoc wireless networks is constrained by the mutual interference of concurrent transmissions between nodes. We study a model of an ad-hoc network where n nodes communicate in random source-destination pairs. These nodes are assumed to be mobile. We examine the per-session throughpu ..."

Power-Aware Routing in Mobile Ad Hoc Networks

by Mike Woo, Suresh Singh, C. S. Raghavendra , 1998
"... In this paper we present a case for using new power-aware metrics for determining routes in wireless ad hoc networks. We present five different metrics based on battery power consumption at nodes. We show that using these metrics in a shortest-cost routing algorithm reduces the cost/packet of rout ..."

Comparison of Broadcasting Techniques for Mobile Ad Hoc Networks

by Brad Williams, Tracy Camp - MOBIHOC'02 , 2002
"... Network wide broadcasting in Mobile Ad Hoc Networks provides important control and route establishment functionality for a number of unicast and multicast protocols. Considering its wide use as a building block for other network layer protocols, the MANET community needs to standardize a single meth ..."

Mitigating routing misbehavior in mobile ad hoc networks

by Sergio Marti, T. J. Giuli, Kevin Lai, Mary Baker - Proc. ACM/IEEE MOBICOM , 2000
"... This paper describes two techniques that improve through-put in an ad hoc network in the presence of nodes that agree to forward packets but fail to do so. To mitigate this prob-lem, we propose categorizing nodes based upon their dynam-ically measured behavior. We use a watchdog that identifies misb ..."

Secure Routing for Mobile Ad Hoc Networks

by Panagiotis Papadimitratos, Zygmunt Haas - MOBILE COMPUTING AND COMMUNICATIONS REVIEW , 2002
"... For such self-organizing infrastructures as mobile ad hoc networks , envisioned to operate in an open, collaborative, and highly volatile environment, the importance of secu- rity cannot be underrated. The provision of comprehen- sive secure communication mandates that both route dis- covery and dat ..."

A Survey of Mobility Models for Ad Hoc Network Research

by Tracy Camp , Jeff Boleng, Vanessa Davies - WIRELESS COMMUNICATIONS & MOBILE COMPUTING (WCMC): SPECIAL ISSUE ON MOBILE AD HOC NETWORKING: RESEARCH, TRENDS AND APPLICATIONS , 2002
"... In the performance evaluation of a protocol for an ad hoc network, the protocol should be tested under realistic conditions including, but not limited to, a sensible transmission range, limited buffer space for the storage of messages, representative data traffic models, and realistic movements of t ..."

of the mobile users (i.e., a mobility model). This paper is a survey of mobility models that are used in the simulations of ad hoc networks. We describe several mobility models that represent mobile nodes whose movements are independent of each other (i.e., entity mobility models) and several mobility models

Location-aided routing (LAR) in mobile ad hoc networks, in:

by Young-Bae Ko , Nitin H Vaidya - Proc. of MOBICOM , 1998
"... A mobile ad hoc network consists of wireless hosts that may move often. Movement of hosts results in a change in routes, requiring some mechanism for determining new routes. Several routing protocols have already been proposed for ad hoc networks. This paper suggests an approach to utilize location ..."

A Review of Current Routing Protocols for Ad-Hoc Mobile Wireless Networks

by Elizabeth M. Royer, Chai-Keong Toh

An ad-hoc mobile network is a collection of mobile nodes that are dynamically and arbitrarily located in such a manner that the interconnections between nodes are capable of changing on a continual basis. In order to facilitate communication within the network, a routing protocol is used to discove ..."
