Digital Channel Modeling and Capacity Calculation for Multi-Relay Multi-Hop Wireless Sensor Networks
نویسندگان
چکیده
This paper presents a new approach for the channel capacity calculation of a multi-relay multi-hop communication system. For the channel model based on Markov chains theory, the exact formula for the channel capacity, which is expressed as a function of packet error rate and number of relays, is derived. The expression of the overall packet error rate is derived in its closed form. The presented theory is supported by numerical analysis. Key-Words: Multi-relay network, Multi-hop network, Digital channel, Channel capacity, Multi-state channel.

A 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 کاملOn Multi-Hop Decode-and-Forward Cooperative Relaying for Industrial Wireless Sensor Networks
Wireless sensor networks (WSNs) will play a fundamental role in the realization of Internet of Things and Industry 4.0. Arising from the presence of spatially distributed sensor nodes in a sensor network, cooperative diversity can be achieved by using the sensor nodes between a given source-destination pair as intermediate relay stations. In this paper, we investigate the end-to-end average bit...
متن کاملMulti-channel Medium Access Control Protocols for Wireless Sensor Networks: A Survey
Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...
