“…The rationale for the system in Figure 1 is available in [ 11 , 12 , 13 ]. Briefly, the probability of a WSAN being k-connected is the same as the probability of all WSAN nodes having a minimum number of neighbors equals to k and depends on the number of deployed nodes n , the node density ρ , defined as n/A , where A is the deployment area, and the nodes’ radio range r , as shown in Equation ( 1 ).…”

The deployment of the nodes in a Wireless Sensor and Actuator Network (WSAN) is typically restricted by the sensing and acting coverage. This implies that the locations of the nodes may be, and usually are, not optimal from the point of view of the radio communication. Additionally, when the transmission power is tuned for those locations, there are other unpredictable factors that can cause connectivity failures, like interferences, signal fading due to passing objects and, of course, radio irregularities. A control-based self-adaptive system is a typical solution to improve the energy consumption while keeping good connectivity. In this paper, we explore how the communication range for each node evolves along the iterations of an energy saving self-adaptive transmission power controller when using different parameter sets in an outdoor scenario, providing a WSAN that automatically adapts to surrounding changes keeping good connectivity. The results obtained in this paper show how the parameters with the best performance keep a k-connected network, where k is in the range of the desired node degree plus or minus a specified tolerance value.

“…All applications are interested in long WSN lifetime. [2,4] The challenge and the motivation of increasing the network lifetime while ensuring a deterministic latency and accuracy is crucial for all the WSN researchers. By increasing the network lifetime and providing a means to ensure the sensed data latency and localization accuracy, we proposed a design and implementation of a WSN node and the energy efficiency in the MAC layer.…”

Abstract-Energy control in Wireless SensorNetwork is one of the most crucial technologies. Based on the acoustic object localization background, we designed a new structure of the sensor node to realize the energy efficiency in the power supply and artificial sleeping scheduling in this paper. The power control model is independent with data processing and control model and can separately realize the power supply for different part of the node. The node can transfer status according the different circumstance to minimize the energy consumption. Furthermore, a new synchronous sleeping/wake schedule mechanism in the medium access control layer is proposed. Sensor nodes can use the forwarding and listening status to schedule their better energy status on demanded. The experiment has been evaluated and analyzed in a test-bed. The result confirms the structure and the proposed mechanism are energy efficiency and gain better trade-off between the accuracy and efficiency.Index terms: Wireless sensor network, scalable architecture, energy-equalize, power control.

In optical sensor networks, the adversary can inject false reports and old packets, both of which can cause false alarms and drain out the limited energy of the network. Existing security mechanisms can detect and filter out only false reports but not the old packets during forwarding. Furthermore, they cannot resist cooperative attacks. A MAC and one-way function based Filtering Scheme (MOFS) was presented. Each node distributes its key and initial hash value to some other nodes after deployment. A data report must carry the MACs and fresh hash values from t detecting nodes. The forwarding nodes check the logicality of the relative position of the detecting nodes carried in the report, the correctness of the MACs and hash values, and the freshness of these hash values. Analysis and simulation results show that MOFS can not only filter false reports and old packets simultaneously, but also performs well on compromise toleration.
