ticularly in office automation. The characteristics and In this paper we propose a decentralized protocol for requirements for their traffic is different I' 2. Data traffic integrated voice and data local area networks. This requires reliable delivery because one bit error may protocol is based on a hybrid token-CSMA/CD protocol destroy the whole message. However, voice traffic is which combine...

Wireless sensor network concept consist sensor nodes which are developed in the specific area senses and transmit data point to point. Delay constraint is the important point in the WSN. The delay guaranteed scheduling and flow control in WSN. Delay guaranteed are important for delay sensitive applications in WSN, Where data delivery is required in a timely manner e.g packet are send if they do...

Many Wireless Sensor Network (WSN) applications necessitate secure multicast services for the purpose of broadcasting delay sensitive data like video files and live telecast at fixed timeslot. This work provides a novel method to deal with end-to-end delay and drop rate of packets. Opportunistic Routing chooses a link based on the maximum probability of packet delivery ratio. Null Key Generatio...

Purpose of review Automated insulin delivery using the subcutaneous site for both glucose sensing and insulin delivery, while not commercially available, is starting to be implemented in the research environment. Here, we review issues with glucose sensing and insulin delivery algorithms that need to be resolved in order to achieve a closed-loop system. Recent findings Glucose sensing technolog...

This paper proposes a trajectory-based optimal area forwarding (TOAF) algorithm tailored for multihop data delivery from infrastructure nodes (e.g., Internet access points) to moving vehicles (infrastructure-to-vehicle) in vehicular ad hoc networks (VANETs) with partial deployment of stationary nodes. It focuses on reducing the delivery-delay jitter and improving the low reliability of infrastr...

In this paper we present a novel energy efficient congestion control scheme for Wireless Multimedia Sensor Network called, CFD (Congestion aware Fair Data delivery). In our proposed CFD mechanism both node level and link level congestions are detected. It ensures fairness of each packet when packet drops happens due to congestion. To avoid congestion a fair rate allocation mechanism is also pro...
