AN ENHANCED D2D RESOURCE ALLOCATION FOR MULTI-HOP WIRELESS SENSOR NETWORKS UNDER HIGH TRAFFIC LOAD

Abstract: The conventional wireless sensor network (WSN) standard of IEEE 802.15.4 is capable of supporting QoS in real-time service by utilizing the guaranteed time slot (GTS) mechanism. However, this GTS allocation policy is not flexible and the increase of end-to-end delay in high traffic load is a very significant network performance degradation factor. In this paper, we propose an enhanced device-to-device (D2D) resource allocation scheme to support the multi-hop network environment. The proposed scheme outperforms other proposed schemes in energy consumption performance, transmission success ratio as well as end-to-end delay performance for supporting multi-hop network under highly loaded network traffic with real-time data transmissions. |
Keywords and phrases: device-to-device communication, multi-hop network, IEEE 802.15.4, guaranteed time slot, wireless sensor networks.
