Healthcare is increasingly becoming a distributed service involving stakeholders and resources who may be physically far from each other. But privacy and security are potential problems. Patient’s data should be available irrespective of their location, but only to authorized person. Not only that, the relationship between the person under observation and other related people, are different and the security and other characteristics concerning the data may also differ accordingly. In this paper we propose a system where an overlay network can be built in an ad hoc basis and links between different entities will be established according to the social relationship between the object person and the person at the other end and the situation of the observed person. Unlike traditional 24-hrs monitoring system, we argued that an ondemand, requirement oriented system will be beneficial for efficient resource utilization, specially in wireless communication.

Annual electric power consumption (EPC) measures the electrification rate of a region. In the present study, annual composites of temporal defense meteorological satellite program/operational line-scan system night time light (NTL) imagery is used as a proxy measure for estimating electrification of India. A regression model is obtained using temporal NTL and EPC data of the region for measuring EPC from NTL data. The model is validated by using NTL data of India aquired during 2013 and is observed to be 99% accurate in measuring EPC from NTL data. The NTL data is also used to estimate population of the region and are found to be positively correlated with each other. The present study supports using the NTL data as a proxy measure of human wellbeing.
