....energy. As battery replacement is practically impossible, low energy consumption is critical [1,2] Radio communications have to be restricted in range and therefore are multi hop in nature. A crucial issue is the observation that every bit transmitted takes a bite out of the node s lifetime [2,3]. We will show that MAC addresses contribute considerably to the header overhead in data packets. In this paper, we focus on the issue of reducing the size of MAC addresses in wireless sensor networks, translating directly in energy savings for data transmissions. Our distributed addressing ....
.... rarely is this used for routing (except for administrative traffic) In addition, instead of forwarding raw sensor data to the end user, nodes process data locally, coordinate amongst neighbors and forward only the aggregated data or decision information, which is around 8 to 16 bytes per packet [1,3]. Since both the packet payload and the destination attribute are very compact, network wide unique MAC addresses, which are used traditionally, represent a huge overhead. For a network of 10,000 nodes, such address requires 14 bits, or about the same as the payload. The MAC addresses, however, ....

....To remedy this problem each group needs to be assigned a group identifier. Also, when a cluster head has advertised its presence, a node which has not found a cluster, and therefore has no address, may want to join. In both the above cases, we use Random, Ephemeral TRansaction Identifiers (RETRI) [13]. RETRI are randomly drawn numbers of a given limited size. They can be used when one needs an identifier that should be unique, but only in a certain place or over a limited period of time. Since a RETRI is probabilistically unique, there is no absolute guarantee about the uniqueness of such an ....

....with scarce resources and evolve once more resources become available. Additionally, the infrastructure should not be inherently dependent on IP as there exist many other environments that do not necessarily use IP for communication, e.g. wireless telephony and distributed sensor networking [7]. The remainder of this paper is divided as follows. Section 2 provides some background information on existing security solutions. In Section 3 we mention the limitations of existing security mechanisms. In Section 4 we discuss the requirements for a cyber security infrastructure for virtual ....
