Abstract

Wireless Personal Area Networks (WPANs) are getting popular in a variety of fields such as home/office automation, e-healthcare, etc. In WPANs, most devices are considerably energy constrained, so the communication protocol should be energy efficient. The IEEE 802.15.4 is designed as a standard protocol for low power, low data rate, low complexity and short range connections in WPANs. The standard supports allocating several number of collision-free Guarantee Time Slots (GTSs) within a superframe for some time-critical transmissions. Recently, COPE was proposed as a promising network coding architecture to essentially improve the throughput of wireless networks. In this paper, we exploit the network coding technique to improve energy efficiency of the WPAN coordinators. We make the WPAN coordinators network coding aware. Some related practical issues, such as GTS allocation and multicast, are also discussed in order to exploit the network coding opportunities efficiently. Since the coding opportunities are mostly exploited, our proposal achieves both higher energy efficiency and throughput performance than the original IEEE 802.15.4.
