Position-based routing protocols forward packets in a greedy manner from source to destination without having to maintain routes through the network. Contention-based routing strategies improve upon position-based routing in that they do not even require t ...
Short Message Service (SMS) has become extremely popular in many countries, and represents a multi-billion dollars market. Yet many consumers consider that the price cellular network operators charge for it is too high. In this paper, we explain that there ...
Many envisioned applications of ad hoc networks involve only small-scale networks that we term Vicinity Ad-hoc Groups (VAGs). Distributed coordination services, instead of pairwise communications, are the primary requirements of VAGs. Existing designs for ...
Position-based routing has proven to be a scalable and efficient way for packet routing in mobile ad-hoc networks. To enable position-based routing, a node must be able to discover the location of the node it wants to communicate with. This task is typical ...
We show in this paper that de Bruijn networks, despite providing efficient search while using constant routing table size, as well as simplicity of the understanding and implementation of such networks, are unsuitable where key distribution will be uneven, ...
P-Grid is a decentralized DHT-based peer-to-peer system with logarithmic search complexity. As it is intended to provide a platform for distributed information management beyond mere file-sharing it supports an update functionality with lazy consistency gu ...
Ultra-Wide Band (UWB) is an emerging wireless physical layer technology that uses a very large bandwidth. We are interested in finding the design objectives of the medium access (MAC, namely, power control and scheduling) and routing protocols of a multi-h ...
Using location information to help routing is often proposed as a means to achieve scalability in large mobile ad-hoc networks. However, location based routing is difficult when there are holes in the network topology and nodes are mobile. Terminode routin ...
Due to the limited number of available IP addresses most computers on the Internet use dynamic IP addresses which causes problems for applications that have to maintain rout-ing tables, for example, peer-to-peer systems. To overcome this we propose unique ...
Increasing application requirements have placed heavy emphasis on building overlay networks to efficiently deliver data to multiple receivers. A key performance challenge is simultaneously achieving adaptivity to changing network conditions and scalability ...
