Real Time Application

Recently, reliable data transport in wireless sensor network becomes very crucial for real-time application with different application requirements. Real time multimedia application requires large bandwidth and big memory in the network in order to send video data and needs to arrive at destination in time. Data that arrives at the receiver not in time will be discarded and cannot be played because loss recovery through retransmission of data loss may introduce long delays. Therefore, an implementation of transport protocol in wireless sensor network for multimedia application is a challenging task. Traditional protocol likes TCP and UDP cannot directly applied for real-time communication over wireless sensor network because the lack of functions of real-time services and the unique characteristics of sensor node itself. However there is another transport protocol which is the Stream Control Transmission Protocol (SCTP) that provides multi-stream service for single connection. This feature can be applied for video transmission according to the type of frame to be transmitted. Thus, to achieve the high reliability video data delivery, the advantages of multi-streaming features in SCTP with the combination of low data rate wireless sensor networks will be applied for the new proposed transport protocol. Besides that, transport protocol algorithm also allows maximum network lifetime due to the limited operating lifetime of sensor node and multimedia also is a highly power consuming task. Thus, to prolong the lifetime of wireless sensor network, an efficient transport protocol need to support reliable message delivery and provide congestion control in the most energy efficient. This paper focuses on the existing transport protocols for real-time application and the future protocol that provides the entire requirement of transport protocol.

In recent years, the research of individual wearable physiological monitoring wireless sensor network is in the primary stage. The monitor of physiology and geographical position used in wearable wireless sensor network requires performances such as real time, reliability, and energy balance. According to these requirements, this paper introduces a design of individual wearable wireless sensor network monitoring system; what is more important, based on this background, this paper improves the classical Collection Tree Protocol and puts forward the improved routing protocol F-CTP based on the fuzzy logic routing algorithm. Simulation results illustrate that, with the F-CTP protocol, the sensor node can transmit data to the sink node in real time with higher reliability and the energy of the nodes consumes balance. The sensor node can make full use of network resources reasonably and prolong the network life.

The progress in the economic society has driven the rapid development of the logistics industry. In the face of increasingly enormous and complicated logistics systems, it is of great practical significance to study how to effectively control the logistics process, minimize the labour cost and provide real-time monitoring data for users. For this purpose, this paper designs an active logistics status tracking (ALST) system platform based on Wireless sensor network (WSN). This paper, by fully integrating the characteristics of WSN, designs the system architecture based on the design philosophy of active logistics status tracking method; it also constructs and realizes the hardware function modules such as wireless sensor node, vehicle gateway, user terminal and backend server etc., and adopts the finite-state machine (FSM)-based active tracking model to maintain the logistics object status; and then it carries out programming of wireless sensor node active state tracking in TinyOS2.x, and finally performs system test under normal operation. The active logistics status tracking system can be widely applied in the logistics industry, to optimize the logistics process, reduce losses and improve logistics operation efficiency.
