The deployment of small cell base stations within the coverage area of a macrocell base station serves as an important means of increasing energy efficiency. Furthermore, such a deployment also constitutes a key technology for future communication network markets. There is a shortage of research, however, on how to efficiently solve the problem of coverage holes (that is, specific locations or areas...
This paper proposes an efficient round-robin-based resource scheduling method performed over both the licensed and unlicensed bands in device-to-device-enabled cellular networks. Simulation results demonstrate that, in terms of the average transmission rate and the blocking ratio, the proposed method is superior to the conventional method.
Understanding per-packet routing dynamics in deployed and complex wireless sensor networks (WSNs) has become increasingly important for many essential tasks such as network performance analysis, operation optimization, system maintenance, and network diagnosis. In this paper, we study routing path recovery for data collection in multi-hop WSNs at the sink using a very small and fixed path measurement...
In this paper, the ASWP testbed, a long-term wireless sensor network (WSN) deployment for environmental monitoring, is presented. This testbed implements a periodic sampling application for external sensors exposed to a forested outdoor environment in western Pennsylvania, USA. It has been running for the past two years using TinyOS-based WSN platforms and the commercially available routing software...
