The specter of nuclear guns didn't fade away with the cave in of the Soviet Union. really, the geopolitical problems of the post-Cold warfare period and the increase of worldwide terrorism have ensured that they continue to be conspicuously current at the international level as a significant foreign main issue. With the 8 or 9 nuclear powers holding approximately 27,000 nuclear guns of their arsenals to today, it's transparent that they're the following to stick for the foreseeable destiny.

Example text

Agent migration is done through cloning or moving [10], it moves by carrying its state, data and code and resumes executing on the new node and no longer exist on the original node. Agent clones by copying its state, data and code to another node and resumes executing on both nodes. Mobile agents systems have added more capabilities to WSN by employing mobile agents that facilitates application re-tasking, local and information processing [9]. J. Baumann et al. [11] have shown that mobile agents have three modes of communication: (1) agent to node: agent accessing the data of the node it’s moving or migrating to; (2) agent to agent: agents exchanging messages between them either locally or remotely; (3) node to agent: node accessing the resources of the agent residing on it.

Case 2: leaving of CH, a cluster member on duty acts as CH as before, moreover, the MCH detects a CH leaved, so the leaved process seems like two leaved members but really one leaved member, one from a cluster and another from the CHs’. In two cases, the leaved process simply takes place in a subgroup as shown in Fig. 8, that depicts key tree structure to generate both group key (KGc) for the cluster of leaved member and group key (KG) for CHs via the same process, while a member leaves the multicast group.

Also, we take the same example used before in this section with leaving M3 in Case 1. The given parameters’ value for each member: g=2, p=13, r’=5 then br’=gr’ mod p=25 mod 13=6, r0 =5 then br0=gr0 mod p=25 mod 13=6. Group key refresh/reinforce: Group key may need to be changed periodically, and may not be related to any change of group membership. The purpose of refreshing the group key periodically is to prevent the long time use of group keys which could be compromised. This process can be implicitly done during the switch of CH, or explicitly performed by CH which generates a new random key r” and multicasts the blinded value br” as well as other intermediate blinded keys.
