Research on Densely-deployed Air Quality Monitoring

Capacity analysis of densely deployed wireless LANs

Wireless LANs (WLANs) based on the IEEE 802.11 standard have become an integral part of today’s indoor wireless communication infrastructure. As WLAN deployments become more prevalent and densely deployed, the nodes in these WLANs start to create congestion and interference with each other. This congestion and interference fundamentally limits the performance of these coexisting WLANs. We analy...

Arduair: Air Quality Monitoring

Air pollution and quality monitoring is extremely important in today’s world as it has a direct impact on human health. Air pollution is on the rise due to a number of anthropogenic activities and its monitoring is of vital importance to mitigate certain measures to control it. In this paper we put forward a low-cost and low-power sensor based system for air quality monitoring. This sensor base...

Quality-of-service Specific Information Retrieval for Densely Deployed Sensor Networks

A new MAC proloco1 is proposed for the reachback opemtiun in large scale, densely deployed sensor networks. Referred to as QUaliryufservice specific Information REtrieval (QUIRE), the proposed protocol aims to assure QoS requirement with a minimum amount of; transmissions from sensors. By enabling only one sensur in a Fghborhood to transmit, QUIRE ensures that the data access point receives no ...

Uniform Segregation of Densely Deployed Wireless Sensor Networks

In wireless sensor networks, the selection of cluster heads relies upon the various selection parameters, such as energy, distance, node concentration and rate of retransmission. There is always uncertainty in the suitability of sensor node for the cluster head role due to these various selection parameters. Fuzzy logic is capable of overcoming uncertainties even with incomplete available infor...
