Abstract:
Cloud computing is fundamental for wireless
sensor network. Firstly massive data is gathered by
Wireless sensor. Then those data is sent to platform of
cloud computing. In the platform data is shared and
transferred. The whole System is controlled and managed.
In the process reliable and integrity of data depends on
performance of wireless sensor Networks Topology control
is one of core key factors which can influence performance
of wireless-sensor networks (WSN). So how to design
topology structure with high reliable and survivability is
becoming the important subject on wireless-sensor
networks. For the issue, a topology evolution strategy
based on scale-free network with energy efficient is
proposed. First by clustering algorithm cluster nodes are
distributed evenly. Then those nodes start evolving in
accordance with random walk processes on scale-free
network. Since some key factors such as residual energy
of node and node degree are taken into account in evolving
procedure, network topology obtains quality features such
as load and energy balance. So the network is quite
practical. Finally the simulation shows that network
topology from the evolution algorithm have good
robustness regardless of deliberate and random attack.
Consequently robustness feature of wireless-sensor
network under severe environment is satisfied.
