In this paper, we present a performance study to evaluate the mean delay and the average system throughput of IEEE 802.11-based wireless local area networks (WLANs). We consider the distributed coordination function (DCF) mode of medium access control (MAC). Stochastic reward nets (SRNs) are used as a modelling formalism as it readily captures the(More)
Problem statement: WiMAX supports multiple types of traffic such as data, voice and video. Each flow requires a certain minimum bandwidth to achieve its QoS. Bandwidth allocation to traffic classes should be in such a way that fairness criteria is met with. Hence, we propose a dynamic bandwidth allocation mechanism to achieve fair and efficient allocation.(More)
The IEEE 802.16 broadband wireless access (BWA) system offers a cost-effective solution to the last-mile wireless connection problem. To provide the necessary QoS guarantees to the multimedia traffic in BWA systems while utilizing the resources as efficiently as possible, optimal scheduling mechanisms and resource allocation strategies are needed.

A dynamic IP address is an IP address that is dynamically assigned to your computer by your Internet service provider (ISP). Once your computer or router is refreshed, your ISP dynamically assigns an IP address to your networking device using DHCP protocol. DHCP follows sequence in assigning an IP address to the host. If a particular host find its IP(More)
Networked robots refer to multiple robots operating together in coordination. This work focuses on the problem of path planning of these robots in an unknown environment with obstacles. In the existing techniques, the robots collaboratively find the location of obstacles and available path and exchange the entire map of the environment among themselves.(More)
AbstructIn this paper, we present a performance analysis of OFDMA based cellular systems with dynamic packet assignment (DPA). Most approaches in the current literature to analyze wireless data networks do not take into account the interference conditions on the radio channel. We propose an analytical model based on a two-dimensional continuous time Markov(More)
College being home away from home for students, expecting multiple facilities is quite demanding. The following paper aims at building an intelligent Mathematical model to categorize and identify the amenities expected by students from a college using a data mining technique called as classification. Data mining, a vital step in ‘Knowledge Discovery in(More)
