This paper presents an overview of random early detection algorithm and differentiated services on ns2. In the present scenario of computer networks the traffic is increasing exponentially due to which packet losses are also increasing at a great rate. An active queue management in routers and gateways can potentially reduce packet loss rates in the Internet. In this paper we have proposed use of...
We consider the problem of centralized routing and scheduling for IEEE 802.16 mesh networks so as to provide Quality of Service (QoS) to individual real and interactive data applications. We first obtain an optimal and fair routing and scheduling policy for aggregate demands for different source- destination pairs. We then present scheduling algorithms which provide per flow QoS guarantees while utilizing...
In this paper we develop and numerically explore the modeling heuristic of using saturation attempt probabilities as state dependent attempt probabilities in an IEEE 802.11e infrastructure network carrying packet telephone calls and TCP controlled file downloads, using enhanced distributed channel access (EDCA). We build upon the fixed point analysis and performance insights. When there are a certain...
