zero can be sent. The symbol rate is one bit per symbol. A more common type of phase modulation is Quadrature Phase Shift Keying (QPSK). It is used extensively in applications including CDMA (Code Division Multiple Access) cellular service‚ wireless local loop‚ Iridium (a voice/data satellite system) and DVB-S (Digital Video Broadcasting — Satellite). Frequency Shift Keying Frequency modulation and phase modulation are closely related. A static frequency shift of +1 Hz means that the phase is constantly

in wired networks‚ wireless communication is not as easy to isolate from attack. The security issues in MANETs are more challenging than those in traditional wired computer networks and the Internet. Providing security in sensor networks is even more difficult than in MANETs due to the resource limitations of sensor nodes and security concerns remain a serious impediment to widespread adoption of these WSNs [27]. Wireless networks have offered attractive flexibility to both network operators
