Heterogeneous Wireless Sensor Networks (HWSN), supported by recent technological advances in low power wireless communications along with silicon integration of various functionalities such as sensing, communications, intelligence, and actuations are emerging as a critically important disruptive computer class based on a new platform, networking structure, and interface that enable novel, low cost, high volume applications such as nuclear, biological, and chemical attack detection and

Several of such applications have been difficult to realize because of problems involved with inputting data from sensors directly into actor systems. To fulfill their large range of applications sensor and actor networks will collaborate with other wired and wireless systems including WLANs, Cellular network, and grid systems. The research community is working to develop high performance computing solutions to problems arising from the complexities of these sensor and actor network systems. This special issue highlights advances in various aspects of heterogeneous wireless sensor networks and is organized from the papers of the 20th International Conference on Advanced Information Networking and Applications AINA, which was held in Vienna University of Technology, Vienna, Austria, April 18-20, 2006. The conference received 521 submissions and every paper was reviewed carefully by 3 reviewers. Based on their quality and significance 153 papers were accepted in AINA-2006. We received 27 papers for this special issue. After two more rounds of review, we accepted 9 papers based on their quality and suitability to the special issue as well as the journal. The tradeoff between efficiency and security is very important is sensor networks. Yin and Madria present an Energy Efficient Secure Routing Protocol for Sensor Networks (ESecRout). The protocol uses the symmetric cryptography to secure messages, and uses a small cache in sensor nodes to record the partial routing path (previous and next nodes) to the destination. It guarantees that the destination will be able to identify and discard the tampered 64 A. Durresi et al. Designing energy efficient hardware for sensor nodes is the primary goal of the research community. In the last paper, Srivastava and Zhang present the design of a CMOS body-bias generating circuit. The authors show that up to 90% leakage current in CMOS circuits can be reduced by applying the adaptive bias generator to lower threshold voltage CMOS circuits. The design is simple and can be embedded in low power CMOS designs such as the physical nodes of wireless sensor networks. Guest Editors Arjan Durresi received the B.E., M.E.. and Ph.D. (all summa cum laude) all in Communications and Applications. He served and is serving at various international conferences such as IEEE ICNP, ACM MobiHoc, DASFAA, and ACM SAC. His research interests include distributed databases, peer-to-peer systems, mobile networks, and mobile computing systems. He is a member of five learned societies, including IEEE and ACM. Leonard Barolli received the B.E. and Ph.D. degrees from Tirana University and
