In view of the functions and requirements of the encrypted traffic adaptive wireless image sensor network based on 6LoWPAN, this paper presents a new scheme of IPV6 header compression which improves the compression ratio of the IPv6 header. Then a modified S-MAC protocol is presented for traffic adaptation and its performance is tested with NS2. The simulation results show that the energy efficiency,...
This paper proposes an adaptive 2 level active period length control method based on traffic load in each cluster for cluster-based wireless sensor networks (WSNs) employing IEEE 802.15.4 medium access control (MAC) protocol. The proposed method consists of two active period length controls: cluster level control and network level control. In the cluster level control, cluster heads autonomously control...
