A, R.Shet, K.C.2020-03-302020-03-302008Proceedings of the 2008 16th International Conference on Advanced Computing and Communications, ADCOM 2008, 2008, Vol., , pp.52-57https://idr.nitk.ac.in/handle/123456789/8384In this paper we present a protocol for group key management in mobile ad hoc networks based on K-dimensional trees, a space partitioning data structure. We use a 2- dimensional tree for a 2 dimensional space. The 2 dimensional tree resembles a binary tree. The protocol reduces the memory requirements for storing the tree by nearly 50% compared to the existing methods and also reduces the number of key changes required whenever membership changes occur. � 2008 IEEE.Book chapter
