    Evaluating a novel cellular automaton based energy -conservating solution in mobile wierless sensor networks
    (Maltepe Üniversitesi, 2009) Javadi, H. Haj Seyyed; Adabi, S.; Rezaee, A.
    According to the traditional definition of wireless sensor networks (WSNs), static sensors have limited the feasibility of WSNs in some kind of approaches, so the mobility was introduced in WSN. Mobile nodes in a WSN come equipped with battery and from the point of deployment; this battery reserve becomes a valuable resource since it cannot be replenished. Hence, maximizing the network lifetime by minimizing the energy is an important challenge in mobile WSN. Energy conservation can be accomplished by different approaches. One approach is utilizing the low-power stand-by mode supported by the wireless devices and adjusting the transmission range on each node. In this paper, an energy conservation solution based on cellular automata is presented. The main objective of this approach is based on dynamically adjusting the transmission range and switching between operational states of the sensor nodes.

    Some results about algebraic properties of generalized cellular automata
    (Maltepe Üniversitesi, 2009) Dadsetani, M. K.; Javadi, H. Haj Seyyed; Adabi, Sa.
    Let G : R A ? R A be a cellular automaton where R is a ring and A is an R-module. In module structure point of view no attempt was made to classify cellular automata (CA). In this presentation we will discuss some properties of linear CA. We prove that if R is a countable ring, G an R-module epimorphism and its restriction to finite configurations is a monomorphism then G is isomorphism.
