Abstract :

               This paper is an RTOS based patient monitoring through WSN without collision. RTOS is a Process which will be done between hardware and application. Here, stack is the one which is used to avoid the independency of the layers from one with another inside the protocol comes under the standard IEEE802.15.4.Stack havingtwo techniques (PAL and NILI) we are using in the IEEE 802.15.4 to reduce the collision and timing.Mostly, during the packets transmission some collision may occur. This collision has to be avoided to prevent the data loss during the transmission.

               The power management system is consists of Zigbee Digital Power meters installed in every consumer unit and an Electricity e-Billing system at the energy provider side. The Zigbee Digital Power meter (ZPM) is a single phase digital kWh power meter with embedded Zigbee modem which utilize the Wireless sensor network to send its power usage reading using information back to the energy provider wirelessly.

               The project deals with the data transmission between two units in the exact time without any collision. The data transmission time is increased with the protocol standard. One of the section runs with RTOS and LPC2148 as master node and another as normal data acquisition node to which sensors are connected. Data acquisition node uses the PIC controller.Communications between two nodes (hardware and application) areaccomplished through IEEE 802.15.4.

               The RTOS is to manage the allocation of these resources to users in an orderly and controlled manner.This wireless sensor node is composed of a micro-processors, transceivers, displays and analog to digital converters.Sensor nodes are deployed for patient monitoring and control.The sensing parameters can be displayed as graph in Master node.The basic view of this technique is to reduce the possibility of collision and to meet the critical requirement of timing for data transmission of patient monitoring applications.
