Wireless Sensor Network2Answer to Question 1IEEE stands for Institute of Electrical and Electronics which has a standard of wirelesslocal area network that is WLAN 802.11 (Ghosh et al., 2012). It has mainly three standard that isIEEE 802.3 for ethernet, IEEE 802.5 which is known as token ring, IEEE 802.11 for mediaaccess control (MAC) (Bloessl et al., 2013). There are three different types of layer that is FHSSwhich stands for frequency hopping spread spectrum, DSSS which stands for direct sequencespread spectrum (DSSS) and IR that is Infrared (Duarte et al.,2012). The above mentioneddifferent layer proved to provide a transmission speed of 2 Mbps. IEEE has two physical layers that is 802.11b and 802.11a, 802.11b has transmission rateof 11 Mbps on the contrary 802.11a has data transmission rate of 54 Mbps (Naraei, Amiri &Saberi, 2014). 802.11b works on the principle of DSSS which is Direct Sequence SpreadSpectrum and 802.11a works on the principle of OFDM which stands for orthogonal divisionmultiplexing. 802.11b operates in the band of 2.4 Ghz and 802.11a operates on the band of 5GHz. Advantage of using 802.11b is that it is generally considered to be low cost, range ofsignal is very good and the signals are not easily obstructed on the contrary it has somedisadvantages like at the of pick of maximum speed it is found to be slowest one and manyhome-based appliances can interfere due to unregulated band of frequency (Ghafouri-Shiraz &Karbassian, 2012). Advantage of using 802.11a is that it provides maximum speed and regulated frequencyprevents the interference of signal form other devices on the contrary it has some disadvantagelike cost is high and signal of short range can be easily obstructed (Naraei, Amiri & Saberi,
Wireless Sensor Network32014). The advantages and disadvantages of 802.11b and 802.11a are opposite to each other(Ghosh et al., 2012).
