Network coding is a promising technique for improving system performance in wireless multihop networks. In this paper, the throughput and fairness in single-relay multi-user wireless networks are evaluated. The carrier sense multiple access with collision avoidance (CSMA/CA) protocol and network coding are used in the medium access control (MAC) sublayer in such networks. The fairness of wirele...

Multi-path is favorite alternative for sensor networks, as it provides an easy mechanism to distribute traffic, as well as considerate fault tolerance. In this paper, a new clustering based multi path routing protocol namely ECRR (Energy efficient Cluster based Routing algorithm for improving Reliability) is proposed, which is a new routing algorithm and guarantees the achievement to required Q...

In recent years, wireless indoor networks have received a lot of scientific and industrial attention. Most systems rely on the use of Orthogonal Frequency Division Multiplexing (OFDM) because of its capability to elegantly cope with multi-path interference. However, while OFDM provides a nice solution for the digital modem, its front-end requirements should be investigated as well. To that goal...

WiMAX is at the peak of communication technology as it is gaining a great position in the next generation of wireless networks. With the development of various wireless networks rapidly, they have turn into necessary infrastructure in our networking atmosphere. The main challenge for WiMAX is the problems associated with various jamming attacks that make them unavailable. Jamming attack is easy...

This study aimed to evaluate the efficiency of energy consumption and economic analysis of different watermelon cultivation systems in Fars Province of Iran. Watermelon production systems were classified into five systems, namely, custom tillage (group 1), conservation tillage (group 2), traditional planting (group3), semi mechanized planting (group 4), and mechanized planting (group 5). Data w...

In this paper, we demonstrate that multiple concurrent asynchronous and uncoordinated Single-Input MultipleOutput (SIMO) transmissions can successfully take place even though the respective receivers do not explicitly null out interfering signals. Thus motivated, we propose simple modifications to the widely deployed IEEE 802.11 MAC to enable multiple nonspatially-isolated SIMO sender-receiver ...

Abstract. In this paper, we propose a new medium access control protocol for wireless sensor networks, named LE-MAC (Latency and Energy aware MAC) that aims to minimize data delivery latency as well as energy consumption. To achieve both goals, we exploit a physical carrier sensing feature in CSMA/CA and combine it with a cross-layer technique. When nodes that are in routing path between source...
