Sparse Multi-hop Wireless for Voice Communication in Rural India
نویسندگان
چکیده
There are many villages in India with sizeable populations that have no means of using telephony for communication within the village. We identify sparse multi-hop wireless networks carrying packetised voice as a quick, cost-e ective and exible solution for rural telecommunication. We discuss design considerations for such a network and de ne a metric called reachability that is useful in evaluating design tradeo s in sparse networks. We present a case study where we use simulation to: i) answer speci c questions related to deployment; and ii) obtain insights into the nature of design tradeo s in such networks.

Multi-hop relay based WiMAX is one of the proposed solutions to address the problem of capacity and coverage expansion in the developing and under-developed regions of the world. Compared with the Point to Multi-Point (PMP) based communication; the mesh mode of WiMAX can provide better coverage, bandwidth, flexibility and scalability. Studies indicate that in rural communities, voice calls and ...
متن کاملA multi-hop PSO based localization algorithm for wireless sensor networks
A sensor network consists of a large number of sensor nodes that are distributed in a large geographic environment to collect data. Localization is one of the key issues in wireless sensor network researches because it is important to determine the location of an event. On the other side, finding the location of a wireless sensor node by the Global Positioning System (GPS) is not appropriate du...
متن کاملAn Adaptive LEACH-based Clustering Algorithm for Wireless Sensor Networks
LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...
متن کاملA Hidden Node Aware Network Allocation Vector Management System for Multi-hop Wireless Ad hoc Networks
Many performance evaluations for IEEE 802.11distributed coordination function (DCF) have been previouslyreported in the literature. Some of them have clearly indicatedthat 802.11 MAC protocol has poor performance in multi-hopwireless ad hoc networks due to exposed and hidden nodeproblems. Although RTS/CTS transmission scheme mitigatesthese phenomena, it has not been successful in thoroughlyomit...
