Quality-of-service Specific Information Retrieval for Densely Deployed Sensor Networks
نویسندگان
چکیده
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 redundant information for reconstrucring the sensedfield within a given maximum distortion (QoS). It jointly'minimizes system latency (the amount of time spent for data co(lection) and total energy consumption (the total number of transmissions from sensors).

متن کاملUncertainty-aware Wireless Sensor Networks
The characterisation of uncertainty and the management of Quality of Service are important issues in mobile communications. In a Wireless Sensor Network, there is a high probability of redundancy, correlation and noise in the sensor features since data is often collected from a large array of densely deployed neighbouring sensors. This article proposes a soft computing approach to manage uncert...
