Adaptive Coordinated Medium Access Control (AC-MAC), a contention-based Medium
Access Control protocol for wireless sensor networks. To handle the load variations in some real-time sensor applications, ACMAC
introduces the adaptive duty cycle scheme within the framework of sensor-MAC (S-MAC).
Pattern-MAC (PMAC) protocol, instead of having fixed sleepwakeups,
the sleep-wakeup schedules of the sensor nodes are
adaptively determined. The schedules are decided based on a
node’s own traffic and that of its neighbors.
nesc language introduction. nesC is an extension to C [2] designed to embody the structuring concepts and execution model of
TinyOS [1]. TinyOS is an event-driven operating system designed for sensor network nodes that
have very limited resources (e.g., 8K bytes of program memory, 512 bytes of RAM). TinyOS has
been reimplemented in nesC. This manual describes v1.1 of nesC, changes from v1.0 are summarised
in Section 3.
The 6.0 release of Visual C++ shows Microsoft s continued focus on Internet technologies and COM, which are key components of the new Windows Distributed interNet Application Architecture (DNA). In addition to supporting these platform initiatives, Visual C++ 6.0 also adds an amazing number of productivity-boosting features such as Edit And Continue, IntelliSense, AutoComplete, and code tips. These features take Visual C++ to a new level. We have tried to make sure that this book keeps you up to speed on the latest technologies being introduced into Visual C++.
Supplemental information for a high-speed serial bus that integrates well with most IEEE standard
32-bit and 64-bit parallel buses is specified. It is intended to extend the usefulness of a low-cost interconnect
between external peripherals, IEEE Std 1394-1995. This standard follows the ISO/IEC 13213:1994 Command
and Status Register (CSR) architecture.

The TJA1040 is an advanced high speed CAN transceiver for use in
automotive and general industrial applications. It supports the differential
bus signal representation described in the international standard for
in-vehicle high speed CAN applications (ISO11898). CAN (Controller Area
Network) is the standard protocol for serial in-vehicle bus communication,
particularly for Engine Management and Body Multiplexing.
The TJA1040 provides a Standby mode, as known from its functional
predecessors PCA82C250 and PCA82C251, but with significantly
reduced power consumption. Besides the excellent low-power behavior
the TJA1040 offers several valuable system improvements. Highlights are
the absolute passive bus behavior if the device is unpowered as well as
the excellent EMC performance.
