Cellular IP: A New Approach to Internet Host Mobility

by András G. Valkó - ACM SIGCOMM , 1999
"... This paper describes a new approach to Internet host mobility. We argue that by separating local and wide area mobility, the performance of existing mobile host protocols (e.g. Mobile IP) can be significantly improved. We propose Cellular IP, a new lightweight and robust protocol that is optimized t ..."

as Internet wireless access becomes ubiquitous. Cellular IP maintains distributed cache for location management and routing purposes. Distributed paging cache coarsely maintains the position of ‘idle ’ mobile hosts in a service area. Cellular IP uses this paging cache to quickly and efficiently pinpoint ‘idle

Integrated Cellular and Ad Hoc Relaying Systems: iCAR

by Hongyi Wu, Chunming Qiao, Swades De, Ozan Tonguz - IEEE Journal on Selected Areas in Communications , 2001
"... Integrated cellular and ad hoc relaying systems (iCAR) is a new wireless system architecture based on the integration of cellular and modern ad hoc relaying technologies. It addresses the congestion problem due to unbalanced traffic in a cellular system and provides interoperability for heterogeneou ..."

for heterogeneous networks. The iCAR system can efficiently balance traffic loads between cells by using ad hoc relaying stations (ARS) to relay traffic from one cell to another dynamically. This not only increases the system's capacity cost effectively, but also reduces transmission power for mobile hosts

Optimal Sequential Paging in Cellular Wireless Networks

by Bhaskar Krishnamachari, RUNG-HUNG GAU, Stephen B. Wicker, Zygmunt J. Haas , 2004
"... In a high-capacity cellular network with limited spectral resources, it is desirable to minimize the radio bandwidth costs associated with paging when locating mobile users. Sequential paging, in which cells in the coverage area are partitioned into groups and paged in a non-increasing order of user ..."

Wireless Cellular Networks

by H. Um, E. J. Delp, Hwayoung Um, Edward J. Delp
"... Abstract — In wireless networks, secure multicast protocols are difficult to implement efficiently due to the dynamic nature of the multicast group and scarcity of bandwidth at the receiving and transmitting ends. Mobility is one of the most distinct features to be considered in a wireless network. ..."

Mining Call and Mobility Data to Improve Paging Efficiency in Cellular Networks

by Hui Zang, Jean C. Bolot , 2007
"... Locating mobile users and devices efficiently is a critical operation in cellular networks. This is done using a combination of location update (by the mobile) and paging (by the network). The paging scheme determines how and where to search for a mobile user given the latest location update informa ..."

A Simple Analysis of Dynamic Location Update Schemes in Cellular Wireless Networks

by Bhaskar Krishnamachari, Stephen Wicker
"... We present a simple first order analysis comparing three dynamic location update schemes that have been proposed for mobility management in cellular networks. The analysis is used to compare the relative performance of the three schemes and to illustrate the tradeoff between the costs of frequent lo ..."

On Wireless Social Community Networks

by Mohammad Hossein Manshaei, Julien Freudiger, Peter Marbach, Jean-pierre Hubaux - In IEEE INFOCOM , 2008
"... Abstract—Wireless social community networks are emerging as a new alternative to providing wireless data access in urban areas. By relying on users in the network deployment, a wireless community can rapidly deploy a high-quality data access infrastructure in an inexpensive way. But, the coverage of ..."
Abstract - Cited by 24 (2 self) - Add to MetaCart
show how the evolution of social community networks depends on their initial coverage, the subscription fee, and the user preferences for coverage. We conclude that by using an efficient static or dynamic pricing strategy, the wireless social community can obtain a high coverage. Using a game

Cellular Automata Based Models of Wireless Sensor Networks

Distributed computation in wireless and dynamic networks

by Rotem Oshman , 2012
"... Today’s wireless networks tend to be centralized: they are organized around a fixed central backbone such as a network of cellular towers or wireless access points. However, as mobile computing devices continue to shrink in size and in cost, we are reaching the point where large-scale ad-hoc wireles ..."
