Secure Routing for Wireless Mesh Sensor Networks in Pervasive Environment

Abstract

Wireless mesh sensor network (WMSN) is a newarchitecture that merges advantages of wireless mesh networks andwireless sensor networks, especially on scalability, robustness andbalanced energy dissipation. Secure routing in WMSNs faces withmore challenges than that in traditional sensor networks by reason ofmultiple sink nodes and the mobility of nodes. In this paper, wepropose a scalable architecture of WMSNs, discuss and analyze keyresearch issues under the proposed architecture, and then design tworouting protocols aiming at minimizing the number of hops between asource node and a destination node and maximizing the lifetime ofsensor networks. Considering new challenges to security in WMSNs,this paper also presents a secure routing protocol SecMLR, whichcan resist most of attacks against routing in WMSNs and work inenergy-efficient ways.
