Distributed TDMA for Privacy Sensitive Anonymous Networks

Free registration required

Executive Summary

This paper proposes a distributed TDMA slot allocation protocol that relies on absolutely no information exchange among the participating nodes. This novel property allows the protocol to work in restricted anonymous environments such as in privacy-sensitive body area networks and various military networks in which nodes may need to cooperate in distributed TDMA but are not allowed to explicitly exchange any information such as node-IDs in order to preserve their anonymity. This paper introduces an innovative approach of time-coded packet transmissions for implicitly exchanging slot timing information. It is shown that using such implicit information, together with a notion of interrupt control packets, the nodes are able to self-allocate collision-free TDMA slots in an anonymous manner.
