actThe collision probability in the MAC layer could become very high when a poor backoff algorithm is used, especially in e networks. The Binary Exponential Backoff (BEB) used in the IEEE 802.11 MAC protocol uses a uniform random distribution oose the backoff value. This often leads to reducing the effect of window size increment. This paper proposes a new(More)
The most known drawback of IEEE 802.11 MAC is the low performance in terms of throughput in case of congested networks. Backoff time is one of the most important factors that govern the collision probability in Ad-Hoc network. Using backoff algorithm could push the performance up and decrease collision rate. This study presents an enhanced fibonacci backoff(More)
In wireless communication environments, backoff is traditionally based on the IEEE binary exponential backoff (BEB). Using BEB results in a high delay in message transmission, collisions and ultimately wasting the limited available bandwidth. As each node has to obtain medium access before transmitting a message, in dense networks, the collision probability(More)

The standard IEEE 802.11 MAC protocol uses the Binary Exponential Backoff algorithm. The Binary Exponential Backoff makes exponential increments to contention window sizes. This work has studied the effect of choosing a combination between linear, exponential and logarithmic increments to contention windows. Results have shown that choosing the right(More)
The aim of this research is to determine if natural language processing techniques can be used to fully automate the extraction of knowledge from emails. The paper reviews the five generations of building systems to share knowledge and highlights the challenges faced by all. The paper discuss the system built by the authors and shows that although the(More)
In wireless communication environments, backoff is traditionally based on the IEEE binary exponential backoff (BEB). As each node has to obtain medium access before transmitting a message, in dense networks, the collision probability in the MAC layer becomes very high when a poor backoff algorithm is used.
