NeTS NOSS: Collaborative Research: Towards Robust and Self-Healing Heterogeneous Wireless Sensor Networks
PI: Dr. Xiaojiang Du
Research has shown that Heterogeneous Sensor Networks (HSNs) can significantly improve the performance of sensor networks. To achieve better performance, we adopt an HSN model consisting of a small number of powerful high-end sensors (H-sensors) and a large number of low-end sensors (L-sensors). The objective of this project is to investigate innovative network architectures of HSNs, and develop energy-efficient, self-healing schemes, routing protocols and security schemes for HSNs.
The main research findings are summarized below:
1) To achieve efficient routing in Heterogeneous Sensor Network (HSN), we proposed an efficient NEar-optiMal rOuting (NEMO) routing protocol.
2) To increase sensor network lifetime, we proposed to use multiple base stations. For multihop sensor networks, we formulated the multiple BSs deployment problems as optimization problems and proposed various optimal or heuristic solutions. In addition, we also designed optimal routing protocol.
3) To protect the source of an event in sensor networks, we designed a lightweight source anonymity protocol for wireless sensor networks.
4) To protect base stations and other important nodes in sensor networks, we developed an efficient anonymous communication protocol for sensor networks. Our protocol can achieve sender/source anonymity, communication-relationship anonymity, and the base station anonymity simultaneously, while having small overheads on computation, storage and communication.
5) We studied the base station (BS) location protection issue. We discovered a new attack on BS: the Parent-based Attack Scheme (PAS). The PAS can locate a BS within one radio (wireless transmission) range of sensors. Different from existing methods, the PAS determines the BS location based on parent-child relationship of sensor nodes. The PAS cannot be defended by existing BS protection schemes. This work leads to a conference paper at the IEEE ICC 2012.
6) Due to the unattended operation nature, nodes in Unattended Wireless Sensor Networks (UWSNs) are susceptible to physical attacks. We investigated how to provide sustainable node self-healing capability for UWSNs. This work leads to a conference paper published at IEEE GLOBECOM 2012.
7) We studied efficient and sustainable self-healing protocols for unattended wireless sensor networks. Analytical and simulation results were published at the IEEE GLOBECOM 2012.
8) We designed secure routing protocols to protect base stations in wireless sensor networks. Results of this work have been published in Wiley Wireless Communications and Mobile Computing in Oct. 2012.
9) A wireless insulin pump may be considered as a wireless sensor node. Wireless insulin pumps have been widely deployed in hospitals and home healthcare systems. Most wireless insulin pumps have limited security mechanisms to protect them from malicious attacks. In this work, we designed effective security schemes to protect wireless insulin pumps. The work has been published in IEEE INFOCOM 2013.
10) We investigated interference mitigation techniques for macro/femto heterogeneous wireless networks. The work has been published in IEEE Wireless Communications Magazine in April, 2013.
11) We studied the coexistence and spectrum sharing of heterogeneous wireless networks (including sensor networks). The work will be published in IEEE
