Conventional wireless sensor networks (WSN) convey information from a set of sensors to the desired destination by mutual collaboration in a multi-hop fashion. This paper presents an IEEE 802.15.4 standard based low power WSN with mobile gateway (MG) which for some applications has advantages over conventional WSN. The MG centric data communication network minimizes the conventional WSN's premature network partition problem i.e. separation of sink due to exhaustion of certain nodes at the stationary sink's one hop distance. Moreover a tree reconfiguration algorithm and two optimization schemes, multiple associations and hybrid tree mesh topology, are proposed in this paper. The presented approach is analyzed and validated in network simulator (NS-2).
