This paper presents the development of a low rate wireless sensor network coordinator with multi-network. This research used small embedded micro controller. The system can expand into multi network and work with single processor. This design will reduce components and power assumption. The research use Propeller Chip by Parrallax Inc. This chip contains eight processors inside. All eight processors can perform tasks simultaneously or with coordination from other processors. It comprised of zigbee chip to perform wireless sensor network that work with 802.15.4 protocol. Experimental results show that we can use single microcontroller work with multi-network. It can monitor result of network directly from Propeller chip by generating computer monitor signal.

This paper presents the development of a low rate and low power consumption wireless sensor network. Wireless sensor networks are cheap and comprised of a small fully autonomous processing communication and sensing devices. The purpose of this study is to develop the system for monitoring and flood warning. They will work with wireless sensor network (WSN) system. WSN has been restricted power supply communication distance and low computing power. But they will work with network in vast area send and receive raw data from each sensor node. It has the ability to cooperatively collect data and retransmit in order to process or alert. The first step of the experiment is creating main node and sub node in flooding area and finds transmission of data between them. When sensor node is not receiving or transmitting data the module can be switched into the sleep mode low power consumption mode

This paper presents the development of a data logger which collects interesting data via low rate wireless sensor network not expensive low power consumed sensor node. The system is wireless and more flexible to expand and substitute sensor nodes by add proper configuration wireless sensor node. System controller uses embedded small multi-code microcontroller Propeller Chip by Parrallax Inc. This chip contains eight processors (Cogs) inside. All eight processors can perform tasks simultaneously or with coordination from other processors. It comprised of Xbee chip to perform wireless sensor network that work with 802.15.4 protocol. Data is collected and stored in Micro SD memory small size and not expensive. It transfer data from data logger to master computer system via wireless network. The experimental results show that we can use single microcontroller based on data logger system small size and flexible. To expand this system with Propeller chip it can monitor data collected by system directly from this chip by generating computer screen monitor signal.

Today wireless sensor networks are developed and comprised of a small fully autonomous processing communication and sensing devices. It has been restricted power supply low computing power. WSNs work in vast area unreachable or crucial area send and receive raw data from each sensor node. It has the ability to cooperatively collect data and retransmit in order to process or alert. This paper used ns-2 simulation propose a power efficient wireless sensor network ant colony system that can adapt it’s function to reduce average energy consumption per node and work in area for a longer time.
