need help how to implement ,two level clustering in WSN to implement a cross layer mac protocol ,each level cluster head decide through the threshold high and threshold low,which is compared to RSS.First level CH will have RSS>thr-high,for the messages send by base station(BS-msgs).This first level CH sends CH-msg,whose RSS is compared to thr-high
There are two types of chips that can connect you to lan. For example, Wiz5100 which implements tcp/ip and other protocol stacks and enc28j60 that implements only mac layer and needs to implement everything else on microcontroller. It depends on what you need. Cheap solution or easy to implement solution...
Hello, I was wondering if I could get some help on implementing "cross layer protocol" or "UW(Underwater)-mac protocol" in matlab? What kind of algorithm could I use? For example: Comparing BER and SNR? Thank you

Hello, Can someone help me with a Matlab code for a simulation of TDMA mac protocol (Wireless networks) using the Poisson Traffic Disytribution? Thank you :|
Hi, I am looking at a very simple embedded web server using a micro controller(LPC1114). Initially I thought to use HTML- TCP - IP & ICMP - SLIP - RS232. In this method, my micro UART was connected to PC serial port. As you see I am not using mac controller in the Link layer, rather using SLIP-Serial Line Internet protocol. Now I come across
I'm looking at protocols like the Aloha protocol at the mac level. How hard is it to programme such protocols (lets say in C language) for real life working devices. where can i learn such low level programming? Does C language have special methods/classes/functions that would help programme mac layer (...)
Is any body may list down MIPS and memory requierment for the following protocol to implement, 1> MODBUS on RS485 2>MBUS 3>DLMS 4>MODBUS on TCP/IP considering i have a controller which has mac/PHY 5>Profibus DP
I have to link a few devices over a local Ethernet LAN. The LAN spans a small building with a few standard 10/100-baseT switches/hubs. Since the devices are very basic, I cant use a full TCP/IP implementation over it. I intend to use the Ethernet protocol without any IP, using only mac adresses. What I need to know is that if that is possible with
There are some options, the one a bit easier to implement than the other: 1. easiest build a top level that includes a uart Tx/Rx and build a simple rs232 communication protocol on the PC 2. moderate same as above but using USB 3. difficult include a ethernet mac/phy in the fpga poll the fpga board through ethernet connecti

Hi friends, In mac layer we ar coming towards two words MSDU(mac service Data Unit) and MPDU(mac protocol Data Unit).What is the difference between these two? Please help me. Thnaks in advance, Goud
hi!I have gone through an ieee paper titled ' FDD mac protocol FOR MULTIMEDIA NETWORKS'.the paper says that bifurcating mac into layers reduces congestion and improves QOS...can someone elaborate on the layers in the present wireless channel and how is it advantageous to further split mac into diff channels.
Bumbar, Wired IP communication systems employ a "layered" network protocol design, made up of 5 layers that perform certain functions in the network. The physical, medium access control (mac)/link and network layers are responsible for network access. FLASH-OFDM takes the same appr
I recently came across an article proposing the implementation of WCDMA using mac protocol. Could someone tell me presently how WCDMA system is being implemented? And what are the advantages of using mac protocol?
Dear Abu Ammora, Layer 2 consist of two (media access control) and LLC (Logical link control), The mac sublayer controls how a computer on the network gains access to the data and permission to transmit it. The LLC layer controls frame synchronization, flow control and error checking. Anyway.... protocol between switch and PC me
Hi guys .. Anyone has any idea about the nature of the interface between the ZigBee silicon part (ZigBee PHY and mac) and the upper ZigBee protocol stack (on a piece of microcontroller) ? And if some one has implemented ZigBee's mac .. did you implement it as complete software running on a microcontroller .. or as hardware same as PHY (...)
basically people implement the 2 lower layers of the network protocol stack .. which are mac and PHY .. usually also people who develope the mac are different from who develope the PHY .. mac can be basically SOFTWARE written on a piece of embedded processor or microcontroller .. and for those parts of the (...)
MII interface is between PHY and mac for 10/100 ethernet and GMII is the interface between the two for Gigabit interface. The PHY will be differeent for the both and the interface signals widths are different for both , PHY is different with respect to decoding and encocoding it does.
Hi, I am looking for a commercial product that implements the 802.11 protocol. Moreover, I want it to have the possiblillity to overcome the existing mac protocol and use another one, created by me. As I have searched to the net I haven't found such possibillity. If anynone knows such a product I would be very grateful. Thanx!
There isn't any direct converter. You should use an ethernet mac. MII is the typical communication protocol between mac and PHY.
If my computer needs to send data to another host on a network halfway around the world, without knowing the mac address, what would the frame format be? For example, within an ethernet network, to send data to another hose in the same network, the sender would include the mac address and the IP address of the receiver host. But if the receiver
I want to implement my new mac layer protocol in real IEEE 802.11 network cards. I think it is not so easy and I should have the WLAN card firmware source code. Do you know where can I find any WLAN firmware source code (to any card, any mac processor)? Maybe you know where to find any other informations that can help to solve my problem. (...)
Hello mahimahi A hardware adress is not 12 bytes long, it is only 48 bits (=6 bytes) long. You can see this also in your ifconfig line: you define it with 6 8-Bit values, this gives 48 bits. The length of this HW-address is fix in the low-level protocol and can not be changed. It is possible, that you set the first I will say 16 bits to zero
