Compressed Sensing Based Joint Rate Allocation and Routing Design in Wireless Sensor Networks

Abstract EN

Compressed sensing for wireless sensor networks has attracted a lot of research attention in the last decade for its advantages in energy saving, robustness, and so on.

Nevertheless, existing solutions mostly focus on the data compression performance while neglecting the energy efficiency.

In this paper, we first present the joint resource allocation problem formulation based on compressed sensing.

Then a distributed algorithm to compute the sampling rate and routes utilizing local network status is proposed.

We conduct extensive experiments based on meteorological wireless sensor networks to verify the merit of our mechanism; it is shown that the proposed mechanism is able to achieve very high efficiency in terms of network lifetime and sensing quality compared with existing approaches.
