Analytical Modeling of IEEE 802.11 Type CSMA/CA Networks with Short Term Unfairness
Abhijit Bhattacharya, Anurag Kumar
We consider single-hop topologies with saturated transmitting nodes, using IEEE~802.11 DCF for medium access. However, unlike the conventional WiFi, we study systems where one or m…
SmartConnect: A System for the Design and Deployment of Wireless Sensor Networks
Abhijit Bhattacharya, Sanjay Motilal Ladwa, Rachit Srivastava +6
We have developed SmartConnect, a tool that addresses the growing need for the design and deployment of multihop wireless relay networks for connecting sensors to a control center.…
A Fast and Accurate Performance Analysis of Beaconless IEEE 802.15.4 Multi-Hop Networks
Rachit Srivastava, Sanjay Motilal Ladwa, Abhijit Bhattacharya +1
We develop an approximate analytical technique for evaluating the performance of multi-hop networks based on beaconless IEEE 802.15.4, a popular standard for wireless sensor networ…
An Approximate Inner Bound to the QoS Aware Throughput Region of a Tree Network under IEEE 802.15.4 CSMA/CA and Application to Wireless Sensor Network Design
Abhijit Bhattacharya, Anurag Kumar
We consider a tree network spanning a set of source nodes that generate measurement packets, a set of additional relay nodes that only forward packets from the sources, and a data…
QoS Constrained Optimal Sink and Relay Placement in Planned Wireless Sensor Networks
Abhijit Bhattacharya, Akhila Rao, K. P. Naveen +3
We are given a set of sensors at given locations, a set of potential locations for placing base stations (BSs, or sinks), and another set of potential locations for placing wireles…
QoS Aware and Survivable Network Design for Planned Wireless Sensor Networks
Abhijit Bhattacharya, Anurag Kumar
We study the problem of wireless sensor network design by deploying a minimum number of additional relay nodes (to minimize network cost) at a subset of given potential relay locat…
