In recent work it has been shown that the use of virtual coordinates or identifiers for efficient routing and data management has several advantages compared to the use of predefined addresses or geographical coordinates. However, these advantages only hold for single domain networks with limited mobility. In this paper, we discuss the challenges arising from using virtual coordinates for routing...
Wireless sensor networks, applied for monitoring physical environments, have recently emerged as an important application of the ad hoc networks paradigm. Low processing power and wireless connectivity make such networks vulnerable to various types of attacks. The dense deployment of sensors along with the protocol deficiencies, make broadcast attacks feasible. The current solutions for these types...
To solve radically the contradiction between the severely limited resource and security for the application in privacy-vital environment in wireless sensor networks (WSNs), we propose a new routing protocol called ITSRP: an Intrusion-tolerant secure routing protocol. We securely and efficiently reconstruct the routing packet in which we design some fields to emphasize the security accounting to the...
